1. Understanding the Need for Comparing Google Sheets
Comparing two Google Sheets and identifying discrepancies is a critical task in various professional and personal scenarios. Whether you’re managing financial records, tracking inventory, or coordinating project tasks, the ability to accurately compare data sets is essential for maintaining data integrity and making informed decisions. This section explores the common reasons and scenarios where comparing Google Sheets becomes necessary.
1.1. Data Reconciliation in Business Operations
In business, data reconciliation involves verifying that data in one system matches the corresponding data in another. This process is crucial for identifying errors, inconsistencies, and discrepancies that can impact financial reporting, inventory management, and customer relationship management.
For example, a company might need to compare sales data from its e-commerce platform with transaction data from its accounting software to ensure that all sales are accurately recorded. Similarly, comparing inventory records from a warehouse management system with sales orders can help identify discrepancies caused by errors in order processing or shipping.
Regular data reconciliation helps businesses maintain accurate records, prevent financial losses, and improve operational efficiency. By identifying and correcting discrepancies promptly, companies can avoid costly errors and make better-informed decisions based on reliable data.
**1.2. Project Management and Task Tracking
Project managers often use Google Sheets to track tasks, deadlines, and resource allocation. Comparing different versions of these sheets can help identify changes, updates, and potential conflicts.
For instance, if multiple team members are updating a project task list, comparing the latest version with a previous one can highlight new tasks, completed tasks, and modifications to deadlines or assignments. This ensures that everyone is aware of the changes and can adjust their work accordingly.
Comparing project sheets also helps in identifying discrepancies in resource allocation. If two sheets show different assignments for the same resource, it can indicate a need for reallocation or clarification to avoid over or underutilization of resources.
**1.3. Financial Record Keeping and Auditing
Accurate financial record-keeping is essential for compliance, tax reporting, and making sound financial decisions. Comparing Google Sheets containing financial data can help identify errors, inconsistencies, and potential fraud.
For example, comparing bank statements with internal accounting records can reveal discrepancies such as unrecorded transactions, incorrect amounts, or unauthorized withdrawals. Similarly, comparing expense reports with receipts can help identify discrepancies and ensure compliance with company policies.
Auditing often involves comparing multiple sets of financial data to verify accuracy and completeness. Comparing Google Sheets can streamline this process by quickly identifying discrepancies and areas that require further investigation.
**1.4. Academic Research and Data Analysis
In academic research, comparing Google Sheets is often necessary for analyzing data collected from different sources or at different times. This can involve comparing survey responses, experimental results, or statistical data.
For example, researchers might compare data from two different surveys to identify trends, patterns, or differences in responses. Similarly, comparing experimental results from different trials can help determine the reliability and validity of the findings.
Comparing Google Sheets also allows researchers to identify and correct errors in data entry or collection. By comparing data sets, researchers can ensure the accuracy and integrity of their findings, leading to more reliable conclusions.
1.5. Personal Use: Budgeting and Planning
Individuals often use Google Sheets for budgeting, financial planning, and tracking personal expenses. Comparing different versions of these sheets can help monitor progress, identify areas for improvement, and make informed financial decisions.
For instance, comparing monthly budget sheets can reveal changes in income, expenses, and savings. This allows individuals to adjust their spending habits and make progress towards their financial goals. Similarly, comparing investment portfolios can help track performance and make informed decisions about asset allocation.
Comparing Google Sheets also helps in identifying discrepancies in personal records. Comparing bank statements with personal expense trackers can reveal unrecorded transactions or errors in categorization.
2. Essential Google Sheets Functions for Comparison
Google Sheets provides several built-in functions that are essential for comparing data and identifying differences between two sheets. These functions allow you to perform a variety of comparison tasks, from simple equality checks to more complex data matching and discrepancy detection.
2.1. VLOOKUP for Matching Data
The VLOOKUP function is a powerful tool for matching data between two Google Sheets. It searches for a specified value in the first column of a range and returns the value in the same row from a specified column.
Syntax:
VLOOKUP(search_key, range, index, [is_sorted])
search_key: The value to search for.range: The range of cells to search in. The first column of this range is where thesearch_keyis searched.index: The column index in the range from which to return a value. The first column in the range is number 1.is_sorted(optional): Indicates if the first column in the range is sorted. It’s recommended to useFALSEfor exact matches.
Example:
Suppose you have two Google Sheets: “Sheet1” with a list of customer IDs in column A and “Sheet2” with a list of customer IDs and their corresponding names in columns A and B, respectively. To find the names of customers in “Sheet1” in “Sheet2”, you can use the following formula in “Sheet1” column B:
=VLOOKUP(A2, Sheet2!A:B, 2, FALSE)
This formula searches for the customer ID in cell A2 of “Sheet1” in the range A:B of “Sheet2” and returns the corresponding name from column B (index 2). If the customer ID is not found, the formula returns #N/A. You can wrap this formula in an IFERROR function to handle errors gracefully:
=IFERROR(VLOOKUP(A2, Sheet2!A:B, 2, FALSE), "Not Found")
2.2. MATCH for Finding Positions
The MATCH function finds the relative position of a specified value in a range. It returns the row or column number where the value is first found.
Syntax:
MATCH(search_key, range, [search_type])
search_key: The value to search for.range: The range of cells to search in.search_type(optional): Specifies the type of match.0for exact match,1for the largest value less than or equal to the search key (range must be sorted in ascending order), and-1for the smallest value greater than or equal to the search key (range must be sorted in descending order).
Example:
To find the row number of a specific product ID in a list of product IDs in “Sheet1” column A, you can use the following formula:
=MATCH("Product123", Sheet1!A:A, 0)
This formula searches for the exact match of “Product123” in column A of “Sheet1” and returns the row number where it is found. If the product ID is not found, the formula returns #N/A.
2.3. COUNTIF and COUNTIFS for Counting Occurrences
The COUNTIF and COUNTIFS functions count the number of cells in a range that meet a specified criterion or multiple criteria.
Syntax:
COUNTIF(range, criterion)
COUNTIFS(range1, criterion1, range2, criterion2, ...)
range: The range of cells to count.criterion: The condition that must be met for a cell to be counted.range1, range2, ...: Additional ranges to evaluate.criterion1, criterion2, ...: Additional criteria to evaluate.
Example:
To count the number of times a specific customer ID appears in a list of customer IDs in “Sheet1” column A, you can use the following formula:
=COUNTIF(Sheet1!A:A, "CustomerID456")
This formula counts the number of cells in column A of “Sheet1” that contain the value “CustomerID456”.
To count the number of orders that meet multiple criteria, such as orders placed in a specific month and with a value greater than a certain amount, you can use COUNTIFS. For example:
=COUNTIFS(Sheet1!B:B, "January", Sheet1!C:C, ">100")
This formula counts the number of orders in “Sheet1” where column B (containing months) is “January” and column C (containing order values) is greater than 100.
2.4. IF for Conditional Checks
The IF function performs a logical test and returns one value if the test is true and another value if the test is false.
Syntax:
IF(logical_expression, value_if_true, value_if_false)
logical_expression: The condition to test.value_if_true: The value to return if the condition is true.value_if_false: The value to return if the condition is false.
Example:
To compare the values in cell A2 of “Sheet1” and cell A2 of “Sheet2” and return “Match” if they are equal and “Mismatch” if they are not, you can use the following formula:
=IF(Sheet1!A2=Sheet2!A2, "Match", "Mismatch")
This formula checks if the value in cell A2 of “Sheet1” is equal to the value in cell A2 of “Sheet2”. If they are equal, it returns “Match”; otherwise, it returns “Mismatch”.
2.5. ISNA and ISERROR for Error Handling
The ISNA and ISERROR functions check if a cell contains an #N/A error or any error, respectively. These functions are useful for handling errors that may occur when using functions like VLOOKUP or MATCH.
Syntax:
ISNA(value)
ISERROR(value)
value: The value to check for an error.
Example:
To check if the VLOOKUP function returns an #N/A error (indicating that the search key was not found), you can use the ISNA function. For example:
=IF(ISNA(VLOOKUP(A2, Sheet2!A:B, 2, FALSE)), "Not Found", VLOOKUP(A2, Sheet2!A:B, 2, FALSE))
This formula first checks if the VLOOKUP function returns an #N/A error. If it does, it returns “Not Found”; otherwise, it returns the value returned by the VLOOKUP function.
To check for any error, including #N/A, #VALUE!, #REF!, etc., you can use the ISERROR function:
=IF(ISERROR(VLOOKUP(A2, Sheet2!A:B, 2, FALSE)), "Error", VLOOKUP(A2, Sheet2!A:B, 2, FALSE))
3. Step-by-Step Guide to Comparing Two Google Sheets
Comparing two Google Sheets to identify differences can seem daunting, but with a systematic approach and the right tools, it can be a straightforward process. This section provides a step-by-step guide to effectively compare two Google Sheets, ensuring data accuracy and saving you time.
3.1. Preparing Your Sheets for Comparison
Before diving into the comparison process, it’s essential to prepare your Google Sheets to ensure accurate and efficient results. This involves organizing your data, ensuring consistency, and cleaning up any discrepancies that might hinder the comparison.
Step 1: Organize Your Data
Ensure that the data in both sheets is organized in a similar format. This includes having the same column headers and data types in corresponding columns. Consistent formatting will make it easier to compare the data accurately.
Step 2: Sort the Data (If Necessary)
If you need to compare rows based on a specific key, such as an ID or date, sort both sheets by that key. Sorting ensures that corresponding rows are aligned, making it easier to identify differences. To sort a sheet, select the data range, go to “Data” in the menu, and choose “Sort range.”
Step 3: Remove Unnecessary Data
Remove any unnecessary columns or rows that are not relevant to the comparison. This will simplify the process and reduce the risk of errors. You can always add the data back later if needed.
Step 4: Clean Up Inconsistencies
Check for inconsistencies in the data, such as variations in spelling, capitalization, or formatting. Use functions like TRIM to remove extra spaces, LOWER or UPPER to standardize capitalization, and SUBSTITUTE to replace specific text strings.
Step 5: Ensure Unique Identifiers
If you are comparing data based on unique identifiers, ensure that these identifiers are indeed unique in both sheets. Duplicate identifiers can lead to inaccurate comparisons. Use the COUNTIF function to identify duplicate values in a column.
3.2. Using VLOOKUP to Find Matches and Differences
The VLOOKUP function is a powerful tool for finding matches and differences between two Google Sheets. It allows you to search for a value in one sheet and retrieve corresponding data from another sheet.
Step 1: Identify the Key Column
Determine the key column that you will use to match rows between the two sheets. This should be a column with unique identifiers, such as an ID, name, or date.
Step 2: Use VLOOKUP to Find Matches
In the first sheet, add a new column to the right of the key column. In the first cell of the new column, enter the VLOOKUP formula to search for the key value in the second sheet and retrieve corresponding data.
For example, if your key column is column A in “Sheet1” and you want to retrieve the corresponding value from column B in “Sheet2”, the formula in “Sheet1” column B would be:
=VLOOKUP(A2, Sheet2!A:B, 2, FALSE)
This formula searches for the value in cell A2 of “Sheet1” in column A of “Sheet2” and returns the corresponding value from column B. The FALSE argument ensures an exact match.
Step 3: Handle Errors
If the VLOOKUP function does not find a match, it returns an #N/A error. To handle this error, wrap the VLOOKUP formula in an IFERROR function:
=IFERROR(VLOOKUP(A2, Sheet2!A:B, 2, FALSE), "Not Found")
This formula returns “Not Found” if the VLOOKUP function returns an #N/A error.
Step 4: Identify Differences
By comparing the retrieved data with the corresponding data in the first sheet, you can identify differences. Use the IF function to compare the values and return a message indicating whether they match or differ.
For example, if you want to compare the value in column C of “Sheet1” with the value retrieved by VLOOKUP from “Sheet2”, the formula in “Sheet1” column D would be:
=IF(C2=IFERROR(VLOOKUP(A2, Sheet2!A:B, 2, FALSE), "Not Found"), "Match", "Difference")
This formula checks if the value in cell C2 of “Sheet1” is equal to the value retrieved by VLOOKUP from “Sheet2”. If they are equal, it returns “Match”; otherwise, it returns “Difference”.
3.3. Conditional Formatting to Highlight Discrepancies
Conditional formatting is a powerful feature in Google Sheets that allows you to automatically format cells based on specified criteria. This can be used to highlight discrepancies between two sheets, making them easier to identify visually.
Step 1: Select the Data Range
Select the data range in the sheet where you want to highlight discrepancies. This should include the columns that you are comparing.
Step 2: Open Conditional Formatting
Go to “Format” in the menu and choose “Conditional formatting.” This will open the Conditional formatting sidebar.
Step 3: Create a New Rule
In the Conditional formatting sidebar, click on “Add another rule.”
Step 4: Set the Formatting Rules
In the “Apply to range” field, ensure that the selected data range is correct.
In the “Format rules” section, choose “Custom formula is” from the “Format cells if” dropdown.
Enter a formula that checks for discrepancies between the two sheets. For example, if you are comparing column C of “Sheet1” with the value retrieved by VLOOKUP from “Sheet2”, the formula would be:
=C2<>IFERROR(VLOOKUP(A2, Sheet2!A:B, 2, FALSE), "Not Found")
This formula checks if the value in cell C2 of “Sheet1” is not equal to the value retrieved by VLOOKUP from “Sheet2”. If they are not equal, the conditional formatting will be applied.
Step 5: Choose the Formatting Style
Choose the formatting style that you want to apply to the cells that meet the criteria. This could include changing the background color, text color, or font style.
Step 6: Save the Rule
Click “Done” to save the conditional formatting rule.
Now, any discrepancies between the two sheets will be automatically highlighted, making them easy to identify visually.
3.4. Using Array Formulas for Advanced Comparisons
Array formulas in Google Sheets allow you to perform calculations on entire arrays of data, rather than just individual cells. This can be used for advanced comparisons between two sheets, such as comparing entire columns or rows at once.
Step 1: Identify the Data Ranges
Determine the data ranges that you want to compare in the two sheets. This could include entire columns or rows.
Step 2: Use Array Formulas to Compare the Ranges
Enter an array formula that compares the data ranges and returns an array of results. For example, if you want to compare column A of “Sheet1” with column A of “Sheet2”, the array formula would be:
=ARRAYFORMULA(IF(Sheet1!A:A=Sheet2!A:A, "Match", "Difference"))
This formula compares each cell in column A of “Sheet1” with the corresponding cell in column A of “Sheet2” and returns “Match” if they are equal and “Difference” if they are not.
Step 3: Display the Results
The array formula will return an array of results that fills the cells below and to the right of the cell where the formula is entered. Ensure that there are enough empty cells to display the entire array of results.
Step 4: Use Conditional Formatting to Highlight Discrepancies
Use conditional formatting to highlight the discrepancies in the array of results. This will make them easier to identify visually.
For example, you can create a conditional formatting rule that highlights the cells in the array that contain the value “Difference.”
3.5. Auditing Changes with Version History
Google Sheets automatically saves a version history of your sheets, allowing you to track changes and revert to previous versions if necessary. This can be a valuable tool for auditing changes and identifying discrepancies between different versions of a sheet.
Step 1: Open Version History
Go to “File” in the menu and choose “Version history” > “See version history.” This will open the Version history sidebar.
Step 2: Browse Previous Versions
In the Version history sidebar, you can browse previous versions of the sheet. Each version is labeled with the date and time it was saved, as well as the name of the user who made the changes.
Step 3: Compare Versions
Select two versions that you want to compare. Google Sheets will highlight the differences between the two versions, making them easy to identify.
Step 4: Restore a Previous Version (If Necessary)
If you identify changes that you want to undo, you can restore a previous version of the sheet by clicking on “Restore this version.”
4. Advanced Techniques for Complex Comparisons
While basic comparison techniques are useful for many scenarios, more complex comparisons require advanced techniques. These techniques involve using a combination of Google Sheets functions and features to handle intricate data structures and comparison requirements.
4.1. Comparing Multiple Columns with ARRAYFORMULA and IF
When you need to compare multiple columns between two Google Sheets, using ARRAYFORMULA in combination with IF can be highly efficient. This allows you to compare entire ranges of data at once and identify discrepancies across multiple criteria.
Step 1: Identify the Columns to Compare
Determine which columns in the two sheets need to be compared. Ensure that the columns have the same data types and are in the same order.
Step 2: Use ARRAYFORMULA and IF to Compare the Columns
Enter an ARRAYFORMULA that uses the IF function to compare the corresponding columns in the two sheets. For example, if you want to compare columns A, B, and C of “Sheet1” with columns A, B, and C of “Sheet2”, the formula would be:
=ARRAYFORMULA(IF((Sheet1!A:A=Sheet2!A:A)*(Sheet1!B:B=Sheet2!B:B)*(Sheet1!C:C=Sheet2!C:C), "Match", "Difference"))
This formula compares each row in columns A, B, and C of “Sheet1” with the corresponding row in columns A, B, and C of “Sheet2”. If all three columns match, it returns “Match”; otherwise, it returns “Difference”.
Step 3: Display the Results
The ARRAYFORMULA will return an array of results that fills the cells below the cell where the formula is entered. Ensure that there are enough empty cells to display the entire array of results.
Step 4: Use Conditional Formatting to Highlight Discrepancies
Use conditional formatting to highlight the discrepancies in the array of results. This will make them easier to identify visually.
For example, you can create a conditional formatting rule that highlights the cells in the array that contain the value “Difference.”
4.2. Using QUERY Function for Data Extraction and Comparison
The QUERY function in Google Sheets allows you to extract and manipulate data from a range based on specified criteria. This can be used to compare data between two sheets by extracting relevant data from each sheet and then comparing the extracted data.
Syntax:
QUERY(data, query, [headers])
data: The range of cells to query.query: The query string that specifies the criteria for extracting data.headers(optional): The number of header rows in the data.
Step 1: Extract Data from the First Sheet
Use the QUERY function to extract the data you want to compare from the first sheet. For example, if you want to extract all rows from “Sheet1” where column A is greater than 100, the formula would be:
=QUERY(Sheet1!A:C, "SELECT * WHERE A > 100")
This formula extracts all rows from columns A, B, and C of “Sheet1” where the value in column A is greater than 100.
Step 2: Extract Data from the Second Sheet
Use the QUERY function to extract the corresponding data from the second sheet. Ensure that the query criteria are the same as in the first sheet.
Step 3: Compare the Extracted Data
Compare the extracted data from the two sheets using functions like IF, MATCH, or VLOOKUP. This will allow you to identify discrepancies and differences between the two sheets.
Step 4: Use Conditional Formatting to Highlight Discrepancies
Use conditional formatting to highlight the discrepancies in the compared data. This will make them easier to identify visually.
4.3. Identifying and Managing Duplicate Entries
Duplicate entries can cause inaccuracies and inconsistencies in your data. Identifying and managing duplicate entries is an important part of comparing two Google Sheets.
Step 1: Identify Duplicate Entries
Use the COUNTIF function to identify duplicate entries in each sheet. For example, if you want to identify duplicate entries in column A of “Sheet1”, the formula would be:
=COUNTIF(Sheet1!A:A, A2)
This formula counts the number of times the value in cell A2 appears in column A of “Sheet1”. If the count is greater than 1, it indicates that the entry is a duplicate.
Step 2: Use Conditional Formatting to Highlight Duplicate Entries
Use conditional formatting to highlight the duplicate entries in each sheet. This will make them easier to identify visually.
For example, you can create a conditional formatting rule that highlights the cells in column A of “Sheet1” where the COUNTIF formula is greater than 1.
Step 3: Remove Duplicate Entries
Once you have identified the duplicate entries, you can remove them manually or by using the “Remove duplicates” feature in Google Sheets.
To remove duplicate entries manually, select the rows that contain the duplicate entries and delete them.
To use the “Remove duplicates” feature, select the data range, go to “Data” in the menu, and choose “Remove duplicates.” Follow the prompts to select the columns to analyze and remove the duplicate entries.
4.4. Combining Functions for Specific Comparison Needs
Combining multiple Google Sheets functions can help you address specific comparison needs and perform complex data analysis.
Example 1: Comparing Data with Multiple Criteria
Suppose you want to compare data in “Sheet1” and “Sheet2” based on multiple criteria, such as customer ID, product ID, and order date. You can use a combination of VLOOKUP, IF, and AND functions to achieve this.
First, use VLOOKUP to retrieve the corresponding data from “Sheet2” based on the customer ID in “Sheet1”. Then, use the IF function to check if the product ID and order date in “Sheet1” match the corresponding values retrieved from “Sheet2”. Use the AND function to combine the multiple criteria.
Example 2: Comparing Data with Fuzzy Matching
Suppose you want to compare data in “Sheet1” and “Sheet2” based on names, but the names may not be exactly the same due to variations in spelling or formatting. You can use a combination of VLOOKUP, IF, and SUBSTITUTE functions to perform fuzzy matching.
First, use SUBSTITUTE to remove any variations in spelling or formatting, such as extra spaces or special characters. Then, use VLOOKUP to retrieve the corresponding data from “Sheet2” based on the cleaned names in “Sheet1”. Finally, use the IF function to check if the retrieved data matches the corresponding data in “Sheet1”.
5. Tips and Best Practices for Efficient Sheet Comparison
Efficiently comparing two Google Sheets requires more than just knowing the right functions; it also involves adopting best practices to streamline the process and minimize errors.
5.1. Structuring Data for Easy Comparison
The way you structure your data can significantly impact the ease and accuracy of comparisons.
- Consistent Column Headers: Ensure that both sheets have the same column headers. Inconsistent headers can lead to confusion and errors when comparing data.
- Standardized Data Types: Use consistent data types for each column. For example, if a column contains dates, ensure that all dates are formatted in the same way.
- Unique Identifiers: Include a unique identifier column in both sheets. This will make it easier to match rows between the two sheets.
- Sorted Data: Sort the data in both sheets by the unique identifier column. This will ensure that corresponding rows are aligned, making it easier to identify differences.
5.2. Leveraging Named Ranges
Named ranges allow you to assign a name to a specific range of cells, making it easier to refer to that range in formulas and functions. This can simplify the comparison process and reduce the risk of errors.
Step 1: Create Named Ranges
Select the data range that you want to name. Go to “Data” in the menu and choose “Named ranges.” Enter a name for the range and click “Done.”
Step 2: Use Named Ranges in Formulas
Use the named ranges in your formulas instead of cell references. This will make your formulas easier to read and understand.
For example, if you have named the data range in “Sheet1” “Sheet1Data” and the data range in “Sheet2” “Sheet2Data”, the VLOOKUP formula would be:
=VLOOKUP(A2, Sheet2Data, 2, FALSE)
5.3. Automating Comparisons with Scripts
For complex or repetitive comparisons, consider using Google Apps Script to automate the process. Google Apps Script is a cloud-based scripting language that allows you to extend the functionality of Google Sheets.
Step 1: Open Script Editor
Go to “Tools” in the menu and choose “Script editor.” This will open the Google Apps Script editor.
Step 2: Write the Script
Write a script that compares the data in the two sheets and identifies the differences. You can use the Google Sheets API to access the data in the sheets and perform the comparison.
Step 3: Run the Script
Run the script to compare the data and generate a report of the differences.
Example Script:
function compareSheets() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet1 = ss.getSheetByName("Sheet1");
var sheet2 = ss.getSheetByName("Sheet2");
var data1 = sheet1.getDataRange().getValues();
var data2 = sheet2.getDataRange().getValues();
// Compare the data in the two sheets
for (var i = 0; i < data1.length; i++) {
for (var j = 0; j < data2.length; j++) {
if (data1[i][0] == data2[j][0]) {
// Compare the other columns
for (var k = 1; k < data1[i].length; k++) {
if (data1[i][k] != data2[j][k]) {
// Log the difference
Logger.log("Difference found in row " + (i + 1) + ", column " + (k + 1));
}
}
}
}
}
}5.4. Verifying Results for Accuracy
Even with the best techniques and practices, errors can still occur. It’s important to verify the results of your comparisons to ensure accuracy.
- Spot-Check Results: Manually review a sample of the results to ensure that the comparisons are accurate.
- Use Multiple Methods: Use multiple comparison methods to verify the results. For example, use both
VLOOKUPandMATCHto compare the data. - Review Formulas: Carefully review your formulas to ensure that they are correct and that they are referring to the correct cells and ranges.
5.5. Troubleshooting Common Issues
When comparing two Google Sheets, you may encounter some common issues. Here are some tips for troubleshooting these issues:
- #N/A Errors: If you are getting
#N/Aerrors in yourVLOOKUPformulas, it means that the search key is not found in the specified range. Check that the search key exists in the range and that the range is correct. - Incorrect Results: If you are getting incorrect results in your comparisons, check that your formulas are correct and that they are referring to the correct cells and ranges. Also, check that the data types in the columns you are comparing are consistent.
- Slow Performance: If your comparisons are running slowly, try reducing the size of the data ranges that you are comparing. Also, try using array formulas instead of individual cell formulas.
