1. Comparing Two Excel Files Side by Side: A Visual Approach
This method is ideal for smaller workbooks where you can visually identify differences. Excel’s View Side by Side mode allows you to arrange two Excel windows next to each other for easy comparison.
1.1. Comparing Two Excel Workbooks Simultaneously
If you have two different Excel workbooks like sales reports for different months, you can view them side by side to easily compare data.
How to do it:
- Open both Excel workbooks.
- Go to the View tab, in the Window group, click the View Side by Side button.
By default, the windows are displayed horizontally. To view them vertically, click the Arrange All button and select Vertical. To synchronize scrolling, ensure the Synchronous Scrolling option is enabled under the View tab, Window group. This allows simultaneous scrolling to compare row by row.
1.2. Arranging Multiple Excel Windows Side by Side for Comprehensive Review
To compare more than two Excel files at once, open all the workbooks and click the View Side by Side button. A dialog box will appear, allowing you to select which files to display alongside the active workbook. Alternatively, use the Arrange All button on the View tab to view all open files in tiled, horizontal, vertical, or cascade arrangements.
1.3. Comparing Two Sheets within the Same Workbook for Detailed Analysis
When the two sheets you need to compare are located in the same workbook, follow these steps:
- Open the Excel file.
- Go to the View tab, Window group, and click the New Window button.
- This will open the same Excel file in a new window.
- Enable View Side by Side mode.
- Select the first sheet in one window and the second sheet in the other window.
2. Formula Method: Comparing Two Excel Sheets for Value Differences
This simple method helps identify cells with different values, creating a difference report in a new worksheet.
How to do it:
- Open a new empty sheet.
- Enter the following formula in cell A1:
=IF(Sheet1!A1 <> Sheet2!A1, "Sheet1:"&Sheet1!A1&" vs Sheet2:"&Sheet2!A1, "")
Copy this formula down and to the right using the fill handle. The formula will adjust based on the relative position of the column and row, comparing corresponding cells in Sheet1 and Sheet2.
2.1. Limitations of Using Formulas for Comparison
While this method is straightforward, it has limitations:
- It only compares values, not formulas or cell formatting.
- It cannot identify added or deleted rows and columns accurately.
- It primarily works on a sheet level and cannot detect workbook-level structural differences.
3. Conditional Formatting: Highlighting Differences Between Two Sheets
Conditional formatting can highlight cells with different values in two sheets using color.
How to do it:
- In the worksheet where you want to highlight differences, select all used cells. Click the upper left cell (usually A1) and press Ctrl + Shift + End.
- On the Home tab, in the Styles group, click Conditional Formatting > New Rule.
- Create a rule with the formula:
=A1<>Sheet2!A1
Where Sheet2 is the name of the other sheet you’re comparing.
Cells with different values will be highlighted with the color you choose.
3.1. Limitations of Conditional Formatting for Comprehensive Comparisons
Like the formula method, conditional formatting has limitations:
- It only finds differences in values and cannot compare formulas or cell formatting.
- It cannot identify added or deleted rows and columns, which can skew results.
- It operates on a sheet level and cannot detect structural differences in the workbook.
4. Compare and Merge Copies of a Shared Workbook: Collaboration Made Easy
The Compare and Merge feature is useful for combining different versions of the same Excel file, especially when multiple users are collaborating.
Prerequisites:
- Share the Excel workbook by clicking the Share Workbook button on the Review tab, in the Changes group, and selecting “Allow changes by more than one user”.
- Each user must save a copy with a unique file name.
4.1. Enabling the Compare and Merge Workbooks Feature
This feature is available in Excel 2010 through Excel 365 but is not displayed by default. To add it to the Quick Access toolbar:
- Open the Quick Access drop-down menu and select More Commands.
- In the Excel Options dialog box, select All Commands under Choose commands from.
- Scroll down to Compare and Merge Workbooks, select it, and click the Add button.

4.2. Comparing and Merging Workbooks: Step-by-Step
- Open the primary version of the shared workbook.
- Click the Compare and Merge Workbooks command on the Quick Access toolbar.
- Select the copies you want to merge in the dialog box. Hold the Shift key to select multiple copies.
- Click OK.
4.3. Reviewing Changes: Identifying Edits Made by Different Users
To see all the edits made by different users at a glance:
- Go to the Review tab, Changes group, and click Track Changes > Highlight Changes.
- In the Highlight Changes dialog, select All in the When box, Everyone in the Who box, clear the Where box, and select the Highlight changes on screen box.
- Click OK.
Excel highlights the column letters and row numbers in dark red, and edits from different users are marked with different colors.
