How To Compare 2 Sheets In Excel: A Comprehensive Guide?

Comparing two sheets in Excel can be challenging, but it’s essential for data analysis and decision-making. COMPARE.EDU.VN provides the solutions and tools you need to effectively compare Excel sheets and identify discrepancies. This guide will explore various methods, from simple visual comparisons to advanced third-party tools, helping you make informed decisions.

1. What Are The Ways To Compare Two Excel Files Side By Side?

Comparing two Excel files side by side is a straightforward method for visually identifying differences. This approach is suitable for smaller workbooks where you can easily spot discrepancies with a keen eye.

1.1 How to Compare 2 Excel Workbooks?

To compare two Excel workbooks side by side, follow these steps:

Open both Excel workbooks you want to compare.
Go to the View tab, locate the Window group, and click View Side by Side.

By default, Excel will arrange the windows horizontally.

To arrange the windows vertically:

Click Arrange All in the Window group.
Select Vertical and click OK.

To enable synchronous scrolling, which allows you to scroll through both worksheets simultaneously:

Ensure the Synchronous Scrolling option is turned on (it’s usually enabled by default when you activate View Side by Side).

1.2 How to Arrange Multiple Excel Windows Side By Side?

To view more than two Excel files at once:

Open all the workbooks you intend to compare.
Click the View Side by Side button. The Compare Side by Side dialog box will appear, allowing you to select the files to display alongside the active workbook.

Alternatively, to view all open Excel files at once:

Click the Arrange All button on the View tab, within the Window group.
Choose your preferred arrangement: tiled, horizontal, vertical, or cascade.

1.3 How to Compare Two Sheets in The Same Workbook?

When the sheets you need to compare are within the same workbook:

Open the Excel file and go to the View tab, then the Window group.
Click New Window. This opens the same Excel file in a new window.
Enable View Side by Side mode by clicking the View Side by Side button.
Select the first sheet in one window and the second sheet in the other window.

2. How to Compare Two Excel Sheets for Differences in Values?

This method uses Excel formulas to create a difference report, highlighting cells with differing values. This is a simple way to identify discrepancies, but it’s limited to value comparisons.

Open a new, blank sheet in Excel.
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 by dragging the fill handle.

This formula compares corresponding cells in Sheet1 and Sheet2. If the values differ, it displays the values from both sheets; otherwise, it leaves the cell blank.

3. How To Highlight Differences Between 2 Sheets With Conditional Formatting?

Conditional formatting is an excellent way to visually highlight cells with different values between two sheets.

Select all the used cells in the worksheet where you want to highlight the differences. Start by clicking the upper-left cell (usually A1) and press Ctrl + Shift + End to extend the selection to the last used cell.
On the Home tab, in the Styles group, click Conditional Formatting > New Rule.
Create a new rule using the formula: =A1<>Sheet2!A1

Replace “Sheet2” with the name of the other sheet you are comparing.

This rule highlights cells in the first sheet that have different values from the corresponding cells in the second sheet, using the color you select.

4. Why Is Comparing And Merging Copies Of A Shared Workbook Important?

Comparing and merging copies of a shared workbook is crucial when multiple users collaborate on the same Excel file. This process ensures that all changes and comments are integrated into a single, cohesive document, reducing conflicts and maintaining data integrity.

4.1 How to Enable the Compare and Merge Workbooks Feature in Excel?

The Compare and Merge Workbooks feature is available in Excel 2010 through Excel 365 but is not displayed by default. To add it to the Quick Access Toolbar:

Click the dropdown menu in the Quick Access Toolbar and select More Commands.
In the Excel Options dialog box, choose All Commands under Choose commands from.
Scroll down to Compare and Merge Workbooks, select it, and click Add to move it to the right-hand section.
Click OK.

4.2 What Are The Steps To Compare and Merge Workbooks?

After enabling the feature:

Open the primary version of the shared workbook.
Click the Compare and Merge Workbooks command in the Quick Access Toolbar.
In the dialog box, select the copies of the shared workbook to merge. Hold the Shift key to select multiple files and click OK.

4.3 How Can Reviewing The Changes Be Helpful?

To see all edits made by different users:

Go to the Review tab, then the Changes group, and click Track Changes > Highlight Changes.
In the Highlight Changes dialog:
- Select All in the When box.
- Select Everyone in the Who box.
- Clear the Where box.
- Check the Highlight changes on screen box.
- Click OK.

Excel highlights the column letters and row numbers with differences in dark red. Edits from different users are marked with different colors at the cell level. Hovering over a cell reveals who made the change.

5. Why Third-Party Tools to Compare Excel Files Are Useful?
