Can You Compare To Excel Spreadsheets? Absolutely! This comprehensive guide from COMPARE.EDU.VN delves into the world of spreadsheet comparison, offering you a detailed exploration of tools and techniques to effectively analyze and identify differences between Excel files. We’ll explore Microsoft Spreadsheet Compare and beyond, providing you with the knowledge to make informed decisions. Discover features, alternatives, and best practices for spreadsheet comparison.
1. What Is Spreadsheet Comparison and Why Is It Important?
Spreadsheet comparison is the process of identifying differences between two or more spreadsheet files. This is important because it ensures data integrity, helps to identify errors, and simplifies collaboration. Analyzing discrepancies is crucial in finance, accounting, data analysis, and any field relying on accurate spreadsheet data.
1.1 Ensuring Data Integrity
Data integrity is paramount in any data-driven field. Regularly comparing spreadsheets helps to confirm the accuracy and consistency of your data, which is critical for making reliable business decisions. Inaccurate data can lead to incorrect analysis, skewed results, and ultimately, flawed business strategies.
1.2 Identifying Errors
Humans make mistakes, especially when manually entering or manipulating data. Spreadsheet comparison tools can quickly flag discrepancies, such as incorrect formulas, transposed numbers, or missing entries. Catching these errors early can prevent costly mistakes and ensure that your reports and analyses are based on accurate information.
1.3 Simplifying Collaboration
When multiple people work on the same spreadsheet, it can be difficult to keep track of all the changes. Spreadsheet comparison tools provide a clear overview of who changed what, when, and where. This transparency simplifies collaboration and reduces the risk of conflicting edits. Tools streamline the reconciliation of different versions of the same file, improving teamwork and productivity.

2.2 How to Open Spreadsheet Compare
- Go to the Start screen.
- Click on Spreadsheet Compare. If you don’t see it, type “Spreadsheet Compare” and select the option.
2.3 Step-by-Step Guide to Comparing Two Excel Workbooks
-
Open the Tool: Launch Spreadsheet Compare.
-
Select Files: Click Home > Compare Files. The Compare Files dialog box will appear.
-
Choose the Earlier Version: Click the blue folder icon next to the Compare box and browse to the location of the older version of your workbook. You can also enter a web address if the file is saved online.
-
Choose the Later Version: Click the green folder icon next to the To box and browse to the location of the newer workbook. Click OK.
Tip: Files can have the same name if they are saved in different folders.
-
Select Comparison Options: In the left pane, select the options you want to include in the comparison results. Options include Formulas, Macros, and Cell Format. You can also click Select All.
-
Run the Comparison: Click OK to start the comparison.
2.4 Understanding the Comparison Results
The comparison results are displayed in a two-pane grid. The left pane shows the “Compare” file (older version), and the right pane shows the “To” file (newer version). The pane below the grids provides details. Changes are highlighted by color.
Key Elements of the Results:
- Side-by-Side Grid: Each worksheet is compared to its counterpart. Use the horizontal scroll bar to navigate multiple worksheets.
- Color-Coded Differences: Differences are highlighted with cell fill colors or text font colors. For example, entered values are green, and changed calculated values are blue-green.
Example:
In the example, results for Q4 in the earlier version were not final. The latest version contains final numbers in the E column for Q4. Cells E2:E5 in both versions have a green fill, indicating that entered values have changed. The calculated results in the YTD column (cells F2:F4 and E6:F6) have a blue-green fill, meaning the calculated value changed.
2.5 Password-Protected Workbooks
If you receive an “Unable to open workbook” message, the workbook might be password-protected. Click OK and enter the password.
2.6 Adjusting Cell Display
If the cells are too narrow to display the content, click Resize Cells to Fit.

4. Advanced Techniques for Spreadsheet Comparison
Beyond the basic comparison tools, several advanced techniques can help you analyze and manage spreadsheet data effectively.
4.1 Using Excel’s Built-in Features
Excel has several built-in features that can aid in comparing spreadsheets. These include conditional formatting, formula auditing, and the INQUIRE add-in.
4.1.1 Conditional Formatting
Conditional formatting can highlight differences between two sets of data within the same spreadsheet. Use rules to highlight cells that are different, duplicated, or unique.
Steps:
- Select the range of cells you want to compare.
- Go to Home > Conditional Formatting > New Rule.
- Choose “Use a formula to determine which cells to format.”
- Enter a formula that compares the selected cell to the corresponding cell in the other data set.
- Set the formatting you want to apply to the differences.
4.1.2 Formula Auditing
Formula auditing tools help you trace precedents and dependents, allowing you to understand how changes in one cell affect others.
Steps:
- Go to the Formulas tab.
- Use the Trace Precedents and Trace Dependents buttons to see how formulas are linked.
- Use Show Formulas to display all formulas in the worksheet.
4.1.3 Inquire Add-in
The INQUIRE add-in, available in some versions of Excel, provides advanced tools for analyzing and comparing workbooks.
Key Features:
- Workbook Analysis: Provides a comprehensive overview of a workbook’s structure, formulas, and errors.
- Workbook Relationship: Shows dependencies between workbooks.
- Compare Files: Runs Spreadsheet Compare directly from Excel.
To enable the INQUIRE add-in:
- Go to File > Options > Add-Ins.
- In the “Manage” dropdown, select “COM Add-ins” and click Go.
- Check the box next to “Inquire” and click OK.
4.2 Using VBA for Custom Comparisons
For more advanced users, VBA (Visual Basic for Applications) can be used to create custom comparison routines. This allows you to tailor the comparison process to your specific needs.
Example VBA Code:
Sub CompareSheets()
Dim ws1 As Worksheet, ws2 As Worksheet
Dim cell1 As Range, cell2 As Range
Dim lastRow As Long, lastCol As Long
' Set the worksheets to compare
Set ws1 = ThisWorkbook.Sheets("Sheet1")
Set ws2 = ThisWorkbook.Sheets("Sheet2")
' Get the last row and column
lastRow = ws1.Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row
lastCol = ws1.Cells.Find("*", SearchOrder:=xlByColumns, SearchDirection:=xlPrevious).Column
' Loop through each cell and compare
For i = 1 To lastRow
For j = 1 To lastCol
Set cell1 = ws1.Cells(i, j)
Set cell2 = ws2.Cells(i, j)
If cell1.Value <> cell2.Value Then
cell1.Interior.Color = vbYellow
cell2.Interior.Color = vbYellow
End If
Next j
Next i
MsgBox "Comparison complete. Differences highlighted in yellow."
End Sub
This code compares two worksheets and highlights any differences in yellow.
4.3 Using Database Comparison Tools
If your spreadsheet data is stored in a database, consider using database comparison tools. These tools are designed to compare data across different databases and can handle large volumes of data efficiently.
