1. Opening Spreadsheet Compare

Question: How do I open Spreadsheet Compare?

Answer: To open Spreadsheet Compare, go to the Start screen and click on Spreadsheet Compare. If you don’t see it, type “Spreadsheet Compare” and select the option.

Spreadsheet Compare is a tool available with Office Professional Plus 2013, Office Professional Plus 2016, Office Professional Plus 2019, or Microsoft 365 Apps for enterprise. It is designed to help you compare two Excel workbooks or versions of the same workbook to find differences, potential problems like manually-entered totals, or broken formulas. In addition to Spreadsheet Compare, there is also a companion program for Access called Microsoft Database Compare, which also requires Office Professional Plus versions or Microsoft 365 Apps for enterprise.

2. Comparing Two Excel Workbooks

Question: What are the steps to compare two Excel workbooks using Spreadsheet Compare?

Answer: To compare two Excel workbooks, click Home > Compare Files. In the dialog box, click the blue folder icon to select the earlier version and the green folder icon to select the workbook you want to compare. Choose your comparison options and click OK.

Here is a more detailed breakdown of the steps:

1. Open Spreadsheet Compare: Launch the application from your Start menu.
2. Select Compare Files: Click on the Home tab, then select Compare Files.
3. Choose the Files:
   • Click the blue folder icon next to the Compare box to browse to the location of the earlier version of your workbook. You can select files saved on your computer, a network, or enter a web address where your workbooks are saved.
   • Click the green folder icon next to the To box to browse to the location of the workbook that you want to compare to the earlier version. Click OK.
4. Choose Comparison Options: In the left pane, select the options you want to see in the comparison results, such as Formulas, Macros, or Cell Format. You can also choose Select All.

If you encounter an “Unable to open workbook” message, it might mean that one of the workbooks is password protected. Click OK and enter the workbook’s password.

3. Understanding Comparison Results

Question: How do I interpret the results after comparing two Excel sheets?

Answer: The comparison results are shown in a two-pane grid. The left pane shows the “Compare” file (typically older), and the right pane shows the “To” file (typically newer). Details are displayed in a pane below the grids, with changes highlighted by color.

Here’s what you need to know to understand the comparison results:

• Side-by-Side Grid: Each worksheet in the first file is compared to the corresponding worksheet in the other file. If there are multiple worksheets, use the forward and back buttons on the horizontal scroll bar to navigate.
• Hidden Worksheets: Even if a worksheet is hidden, it is still compared and displayed in the results.
• Color Highlighting: Differences are highlighted with cell fill colors or text font colors, depending on the type of difference. For example, cells with “entered values” (non-formula cells) are formatted with a green fill color in the side-by-side grid and with a green font in the pane results list. A legend in the lower-left pane explains what the colors mean.

For example, if the results for Q4 in an earlier version of a workbook were not final, the latest version containing the final numbers will show changes in the respective cells. Cells with changed entered values will have a green fill, while cells with changed calculated values will have a blue-green fill.

4. Dealing with Narrow Cells

Question: What should I do if the cells are too narrow to show the contents in the comparison results?

Answer: If the cells are too narrow to display the cell contents, click Resize Cells to Fit to adjust the column widths.

This ensures that you can view all the data within the cells, making it easier to identify and understand the differences between the two workbooks.

5. Using Excel’s Inquire Add-in

Question: How can Excel’s Inquire add-in help in comparing spreadsheets?

Answer: Excel 2013 and later versions have an Inquire add-in that, once enabled, provides an “Inquire” tab. From this tab, you can analyze a workbook, view relationships between cells, worksheets, and other workbooks, and remove excess formatting.

Here’s how the Inquire add-in enhances spreadsheet comparison:

1. Analyze Workbook: Helps to understand the structure and dependencies within the workbook.
2. Show Relationships: Visualizes the connections between cells, worksheets, and other workbooks.
3. Clean Excess Formatting: Removes unnecessary formatting to simplify the workbook.

To use the Inquire add-in, you first need to enable it. If you don’t see the Inquire tab in Excel, go to File > Options > Add-Ins. In the Manage box, select COM Add-ins and click Go. Check the Inquire box and click OK to activate the add-in.

6. Running Spreadsheet Compare from Excel

Question: Can I run Spreadsheet Compare directly from Excel?

Answer: Yes, if you have two workbooks open in Excel, you can run Spreadsheet Compare by using the Compare Files command within the Inquire add-in.

This provides a convenient way to quickly launch the comparison tool without having to open Spreadsheet Compare separately.

7. Managing Mission-Critical Files

Question: What tools can help manage mission-critical Excel and Access files?

Answer: For organizations with mission-critical Excel workbooks or Access databases, consider installing Microsoft’s spreadsheet and database management tools like Microsoft Audit and Control Management Server and Microsoft Discovery and Risk Assessment Server.

These tools offer powerful change management and inventory analysis features to help reduce the risk associated with using end-user-developed tools in Excel and Access.

8. Alternative Methods for Comparing Excel Sheets

Question: What are some alternative methods to compare information in two Excel sheets besides using Spreadsheet Compare?

Answer: Besides Microsoft Spreadsheet Compare and the Inquire add-in, you can use several other methods to compare information in two Excel sheets, including conditional formatting, formulas, and third-party tools.

a. Conditional Formatting

Conditional formatting is a powerful Excel feature that allows you to highlight differences and similarities between two sheets directly within Excel. Here’s how you can use it:

1. Open Both Sheets: Open the two Excel sheets you want to compare in the same workbook or in separate instances of Excel.
2. Select the Data Range: In the first sheet, select the range of cells you want to compare.
3. Apply Conditional Formatting:
   • Go to the Home tab.
   • Click on Conditional Formatting.
   • Select New Rule.
4. Create a New Rule:
   • Choose Use a formula to determine which cells to format.
   • Enter a formula that compares the selected range with the corresponding range in the second sheet. For example, if you are comparing Sheet1!A1:C10 with Sheet2!A1:C10, you can use the formula =A1<>Sheet2!A1.
   • Click on Format to choose how you want the differences to be highlighted (e.g., fill color, font color).
   • Click OK to apply the rule.

Now, any differences between the two sheets will be highlighted according to the format you chose.

b. Formulas

Excel formulas can be used to compare data and return specific results based on whether the data matches or differs. Here are a few useful formulas:

1. EXACT Function:

   • The EXACT function compares two text strings and returns TRUE if they are exactly the same, and FALSE otherwise. It is case-sensitive.
   • Syntax: =EXACT(text1, text2)
   • Example: =EXACT(A1, Sheet2!A1)

2. IF Function:

   • The IF function can be used to perform different actions based on whether a condition is met.
   • Syntax: =IF(condition, value_if_true, value_if_false)
   • Example: =IF(A1=Sheet2!A1, "Match", "Mismatch")

3. COUNTIF Function:

   • The COUNTIF function counts the number of cells within a range that meet a given criteria.
   • Syntax: =COUNTIF(range, criteria)
   • Example: =COUNTIF(Sheet2!A1:A10, A1) (This counts how many times the value in A1 of the first sheet appears in the range A1:A10 of the second sheet)

c. Using VBA (Visual Basic for Applications)

For more complex comparisons, you can use VBA to write custom scripts that compare data and highlight differences. Here’s a basic example:

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

    ' Set the worksheets to compare
    Set ws1 = ThisWorkbook.Sheets("Sheet1")
    Set ws2 = ThisWorkbook.Sheets("Sheet2")

    ' Get the last row with data in the first sheet
    lastRow = ws1.Cells(Rows.Count, "A").End(xlUp).Row

    ' Loop through each row
    For i = 1 To lastRow
        ' Compare values in column A
        If ws1.Cells(i, "A").Value <> ws2.Cells(i, "A").Value Then
            ' Highlight differences
            ws1.Cells(i, "A").Interior.Color = vbYellow
            ws2.Cells(i, "A").Interior.Color = vbYellow
        End If
    Next i

    MsgBox "Comparison complete!"
End Sub

This VBA script compares the values in column A of two sheets and highlights any differences in yellow.

d. Third-Party Tools

Several third-party tools are designed specifically for comparing Excel files. These tools often provide more advanced features and a user-friendly interface. Some popular options include:

• Synkronizer Excel Compare: Offers detailed comparison reports and can identify differences in formulas, values, and formatting.
• XL Comparator: Highlights differences in data and formulas, and provides tools for merging changes.
• Araxis Excel Compare: Integrates with Excel and provides a visual comparison of worksheets.
