Explore effective strategies for Excel sheet comparison, data matching, and discrepancy detection to streamline your workflow.
1. Comparing Two Excel Files Side-by-Side: A Visual Approach
If you’re dealing with relatively small workbooks and have a keen eye for detail, the “View Side by Side” mode in Excel can be a quick and easy way to compare files. This feature allows you to arrange two Excel windows next to each other for visual comparison, whether it’s two separate workbooks or two sheets within the same workbook.
1.1. Comparing Two Excel Workbooks
Imagine you have sales reports for two different months, and you want to see them simultaneously to understand which products performed better in each period. Here’s how to open two Excel files side by side:
- Open both workbooks you want to compare.
- Go to the View tab, find the Window group, and click the View Side by Side button.
By default, Excel displays the two windows horizontally. If you prefer a vertical arrangement, click the Arrange All button and select Vertical. To scroll through both worksheets simultaneously, ensure that the Synchronous Scrolling option is enabled. This option is usually activated automatically when you use the View Side by Side mode.
1.2. Arranging Multiple Excel Windows Side-by-Side
If you need to view more than two Excel files at once, open all the workbooks you want to compare and click the View Side by Side button. A dialog box will appear, allowing you to select the files to display alongside the active workbook. To view all open Excel files at once, click the Arrange All button on the View tab and choose your preferred arrangement: tiled, horizontal, vertical, or cascade.
1.3. Comparing Two Sheets in the Same Workbook
Sometimes, the two sheets you want to compare are located in the same workbook. To view them side by side, follow these steps:
- Open your Excel file, go to the View tab, and click the New Window button in the Window group.
- This will open the same Excel file in a separate window.
- Enable View Side by Side mode by clicking the corresponding button on the ribbon.
- Select the first sheet in the first window and the second sheet in the second window.
2. Formula-Based Comparison: Identifying Differences in Values
This straightforward method allows you to compare data in Excel and pinpoint cells with different values, creating a difference report in a new worksheet. To compare two Excel worksheets for differences, open a new, empty sheet, enter the following formula in cell A1, and then copy it down and to the right using the fill handle:
=IF(Sheet1!A1<>Sheet2!A1, "Sheet1:"&Sheet1!A1&" vs Sheet2:"&Sheet2!A1, "")
The formula uses relative cell references, so it adjusts based on the column and row position. The formula in A1 compares cell A1 in Sheet1 and Sheet2, the formula in B1 compares cell B1 in both sheets, and so on.
This formula compares the two sheets, identifies cells with different values, and displays the differences in the corresponding cells.
3. Conditional Formatting: Highlighting Differences Between Two Sheets
To visually highlight cells with different values in two sheets using a color of your choice, use Excel’s conditional formatting feature:
- In the worksheet where you want to highlight differences, select all used cells. Click the upper-left cell of the used range, 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, and create a rule with the following formula:
=A1<>Sheet2!A1
Replace “Sheet2” with the name of the other sheet you are comparing.
With this rule in place, cells with different values will be highlighted with the selected color.
4. Compare and Merge Copies of a Shared Workbook
When you need to merge different versions of the same Excel file, the Compare and Merge feature is invaluable, especially when multiple users are collaborating on the same workbook. This feature allows you to view the changes and comments of all users simultaneously. To use this feature effectively, ensure the following:
- Share your Excel workbook before making it available to other users. Click the Share Workbook button on the Review tab, in the Changes group, select the Allow Changes by More Than One User… box, and click OK. Allow Excel to save the workbook if prompted. Turning on the Track Changes feature shares the workbook automatically.
- Each person who edits the shared workbook must save a copy (.xls or .xlsx file) with a unique file name.
4.1. Enabling the Compare and Merge Workbooks Feature
The Compare and Merge Workbooks feature is available in all versions of Excel from 2010 through Excel 365, but it’s 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.
- In the list of commands, scroll down to Compare and Merge Workbooks, select it, and click the Add button to move it to the right-hand section.
- Click OK.
4.2. Comparing and Merging Workbooks
Once all users have finished working with the shared Excel workbook, you can merge all the copies into one file:
- Open the primary version of the shared workbook.
- Click the Compare and Merge Workbooks command on the Quick Access toolbar.
- In the dialog box, select a copy of the shared workbook to merge. To select multiple copies, hold the Shift key while clicking the file names, and then click OK.
The changes from each copy are merged into a single workbook.
4.3. Reviewing Changes
To see all the edits made by different users at a glance:
- Go to the Review tab, in the 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, select the Highlight changes on screen box, and click OK.
Excel highlights column letters and row numbers in dark red to indicate rows and columns with differences. Edits from different users are marked with different colors at the cell level. Hover over a cell to see who made a specific change.
5. Third-Party Tools to Enhance Excel File Comparison
While Microsoft Excel provides several features for comparing data, none of the built-in options can comprehensively compare Excel sheets or entire workbooks, spotting all differences in values, formulas, or formatting. Third-party tools are designed to provide advanced and efficient means to compare, update, and merge Excel sheets and workbooks. Here are a few tools that stand out:
5.1. Synkronizer Excel Compare: A 3-in-1 Tool
The Synkronizer Excel Compare add-in can quickly compare, merge, and update two Excel files, saving you the trouble of searching for differences manually. Key features include:
- Identifying differences between two Excel sheets.
