4. Understanding The Results Of An Excel File Comparison

Understanding the results of an Excel file comparison is crucial for identifying discrepancies and ensuring data integrity. The comparison process, whether using Microsoft Spreadsheet Compare or the Inquire add-in, highlights differences between two versions of a workbook. Here’s how to interpret these results effectively.

4.1 Key Elements of Comparison Results

Side-by-Side Grid:
- The comparison results are typically displayed in a two-pane grid. The workbook on the left corresponds to the “Compare” file (usually the older version), while the workbook on the right corresponds to the “To” file (usually the newer version).
Worksheet Navigation:
- Each worksheet in one file is compared to the corresponding worksheet in the other file. If there are multiple worksheets, you can navigate between them using the forward and back buttons on the horizontal scroll bar.
Color-Coded Highlighting:
- Differences between the files are highlighted using different colors. The type of change (e.g., formula, value, format) determines the color used.

4.2 Interpreting Color Codes

The color codes used in the comparison results provide valuable information about the types of changes that have been made. Here’s a breakdown of common color codes and their meanings:

Green Fill or Font:
- Indicates that an entered value (a non-formula cell) has changed. This means the actual data in the cell has been modified.
Blue-Green Fill:
- Indicates that a calculated value has changed. This means the formula in the cell has remained the same, but the result of the calculation has changed due to changes in the input values.
Other Colors:
- Depending on the comparison tool and settings, other colors may be used to indicate different types of changes, such as changes in formulas, cell formatting, or structural differences (e.g., added or deleted rows/columns). Always refer to the legend provided with the comparison results to understand the specific meanings of each color.

4.3 Analyzing Specific Changes

Identifying Changed Values:
- When you see a cell with a green fill, it means the value in that cell has been directly modified. Check the corresponding cell in the other version of the workbook to see the original value and understand the change.
Investigating Formula Changes:
- If a cell has a blue-green fill, it indicates that the calculated value has changed. This could be due to changes in the input values or modifications to the formula itself. To investigate, examine the formula in both versions of the workbook to see if it has been altered.
Checking for Formula Errors:
- Sometimes, a change in a calculated value can reveal an underlying issue with the formula. For example, a formula might be referencing the wrong cells or omitting a necessary range. By comparing the formulas in both versions, you can identify and correct these errors.

4.4 Example Scenario

Consider a scenario where you are comparing two versions of a sales report. In the earlier version, the Q4 sales numbers were not final. The updated version contains the final numbers in the E column for Q4.

Cells E2:E5 in both versions have a green fill: This indicates that the entered values in these cells have changed, reflecting the updated Q4 sales figures.
The calculated results in the YTD column (cells F2:F4 and E6:F6) have a blue-green fill: This means the calculated values in these cells have changed because the input values (Q4 sales) have been updated.
Cell F5 also changed, and the formula in the earlier version was incorrect (it only summed B5:D5, omitting the value for Q4): The updated workbook corrected the formula in F5 to =SUM(B5:E5). This highlights how the comparison process can reveal and correct errors in formulas.

4.5 Additional Tips

Use the Legend:
- Always refer to the legend provided with the comparison results to understand the meaning of each color code.
Resize Cells to Fit:
- If the cells are too narrow to display the contents, click Resize Cells to Fit to see the full data.
Review Hidden Worksheets:
- Remember that hidden worksheets are also compared and displayed in the results. Make sure to review these sheets as well to identify any changes.

8. Advanced Tips For Excel File Comparison

To maximize the effectiveness of Excel file comparison, consider these advanced tips that go beyond the basic functionalities:

8.1 Using Conditional Formatting

Conditional formatting can highlight differences directly within Excel, making it easier to spot discrepancies before even using a comparison tool.

Highlight Unique Values:
- Select the range of cells you want to compare in both spreadsheets.
- Go to Home > Conditional Formatting > Highlight Cells Rules > Duplicate Values.
- Change the dropdown from “Duplicate” to “Unique”.
- Choose a formatting style to highlight the unique values.
- This will highlight cells that are different between the two ranges.
Highlight Differences Based on Formulas:
- You can use a formula to compare cell values and apply formatting accordingly.
- Select the range of cells in your primary spreadsheet.
- Go to Home > Conditional Formatting > New Rule.
- Select “Use a formula to determine which cells to format”.
- Enter a formula like =A1<>Sheet2!A1 (assuming you are comparing Sheet1 to Sheet2 and starting at cell A1).
- Set the desired formatting and click OK.

8.2 Leveraging the VLOOKUP Function

VLOOKUP is a powerful function to compare data across two spreadsheets by searching for values in one sheet and returning corresponding values from another.

Finding Missing Data:
- In your primary spreadsheet, add a new column.
- Use the VLOOKUP function to search for values from the primary sheet in the secondary sheet.
- For example: =VLOOKUP(A1,Sheet2!A:B,2,FALSE). This searches for the value in A1 of the current sheet within columns A and B of Sheet2 and returns the value from column B if a match is found.
- If VLOOKUP returns #N/A, the value in the primary sheet is not found in the secondary sheet.
Comparing Corresponding Values:
- Use VLOOKUP to retrieve corresponding values and compare them directly.
- In a new column, use the formula to fetch the corresponding value and then compare it to the value in the primary sheet.
- For example: =IF(B1=VLOOKUP(A1,Sheet2!A:B,2,FALSE),"Match","Mismatch").

8.3 Creating Pivot Tables for Comparison

Pivot tables can summarize and compare data from multiple sources, making it easier to identify differences.

Consolidating Data:
- If your data is in a consistent format, consolidate it into a single sheet.
- Add a column to indicate the source of the data (e.g., “Version1”, “Version2”).
Creating the Pivot Table:
- Select your consolidated data.
- Go to Insert > PivotTable.
- Drag the source column to the “Columns” area.
- Drag the categories you want to compare to the “Rows” area.
- Drag the values you want to compare to the “Values” area.
- The pivot table will display the data from each source side-by-side, making it easy to spot differences.

8.4 Using Array Formulas for Complex Comparisons

Array formulas allow you to perform complex calculations and comparisons across multiple cells.

Comparing Entire Rows or Columns:
- Select a range of empty cells where you want the comparison results to appear.
- Enter the array formula. For example, to compare row 1 in Sheet1 and Sheet2: ={IF(Sheet1!1:1=Sheet2!1:1,"Match","Mismatch")}.
- Press Ctrl + Shift + Enter to enter the formula as an array formula.
- This will compare each cell in the row and display “Match” or “Mismatch” accordingly.
Counting Differences:
- Use an array formula to count the number of differences between two ranges.
- For example: ={SUM(IF(Sheet1!A1:A10<>Sheet2!A1:A10,1,0))}.
- Press Ctrl + Shift + Enter to enter the formula as an array formula.
- This will return the number of cells that are different between the two ranges.

8.5 Automating Comparisons with VBA

For repetitive comparison tasks, consider using VBA (Visual Basic for Applications) to automate the process.

Writing a VBA Script:
- Open the VBA editor by pressing Alt + F11.
- Insert a new module by going to Insert > Module.
- Write a VBA script to compare the two sheets. Here’s a simple example:

Sub CompareSheets()
    Dim ws1 As Worksheet, ws2 As Worksheet
    Dim i As Long, lastRow As Long

    Set ws1 = ThisWorkbook.Sheets("Sheet1")
    Set ws2 = ThisWorkbook.Sheets("Sheet2")

    lastRow = ws1.Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row

    For i = 1 To lastRow
        If ws1.Cells(i, 1).Value <> ws2.Cells(i, 1).Value Then
            Debug.Print "Difference at row " & i
            ' You can add code here to highlight the differences
        End If
    Next i

    MsgBox "Comparison complete. Check the Immediate Window (Ctrl+G) for differences."
End Sub

Run the script by pressing F5.
The script will compare the values in the first column of Sheet1 and Sheet2 and print the row number where differences are found in the Immediate Window (Ctrl+G).

8.6 Ensuring Data Consistency

Standardize Data Entry:
- Ensure that data is entered consistently across all spreadsheets. Use data validation rules to enforce standard formats for dates, numbers, and text.
Use Consistent Formulas:
- Ensure that formulas are consistent across all spreadsheets. Use named ranges to make formulas more readable and less prone to errors.
Regularly Audit Data:
- Schedule regular audits of your data to identify and correct any inconsistencies or errors. Use Excel’s built-in auditing tools to trace dependencies and identify potential problems.
