Navigating the world of spreadsheets often leads to the need to compare two Excel sheets. Whether you’re reconciling data, identifying discrepancies, or merging information, the process can be time-consuming and prone to error. At COMPARE.EDU.VN, we understand these challenges and offer solutions to make Excel sheet comparison easy. Let’s delve into effective techniques and tools to streamline this essential task.
1. Comparing Two Excel Sheets by Viewing Them Side by Side
One of the simplest methods to compare two Excel sheets is by viewing them side by side. This approach is effective for smaller datasets where you can visually identify differences.
1.1 Comparing 2 Excel Workbooks
Comparing two separate Excel workbooks side by side allows for quick visual assessment. Here’s how to do it:
- Open the Workbooks: Open both Excel files you want to compare.
- View Side by Side: Go to the View tab, in the Window group, and click the View Side by Side button.
Excel will arrange the two workbooks side by side, either horizontally or vertically. To change the arrangement to vertical, click Arrange All and select Vertical.
1.2 Synchronous Scrolling
To scroll through both worksheets simultaneously, ensure the Synchronous Scrolling option is turned on. This option, located on the View tab under Window, is usually enabled automatically when you activate the View Side by Side mode.
1.3 Arranging Multiple Excel Windows
If you need to compare more than two Excel files, follow these steps:
- Open All Workbooks: Open all the Excel files you intend to compare.
- View Side by Side: Click the View Side by Side button. The Compare Side by Side dialog box will appear.
- Select Files: Choose the files to be displayed along with the active workbook.
To view all open Excel files at once, click Arrange All in the View tab and select your preferred arrangement: tiled, horizontal, vertical, or cascade.
1.4 Comparing Two Sheets in the Same Workbook
Sometimes, the sheets you want to compare are within the same workbook. Here’s how to view them side by side:
- Open a New Window: Open the Excel file, go to the View tab, and click New Window.
- Enable View Side by Side: This opens the same file in a new window. Enable View Side by Side mode.
- Select Sheets: Choose the first sheet in one window and the second sheet in the other window.
2. Using Formulas to Compare Two Excel Sheets for Differences in Values
For a straightforward comparison of values, you can use Excel formulas to identify cells with different values, creating a difference report.
2.1 Creating a Difference Report
- Open a New Sheet: Open a new, blank sheet in your Excel workbook.
- Enter the Formula: In cell A1, enter the following formula:
=IF(Sheet1!A1 <> Sheet2!A1, "Sheet1:"&Sheet1!A1&" vs Sheet2:"&Sheet2!A1, "")- Copy the Formula: Drag the fill handle (the small square at the bottom right of the cell) down and to the right to apply the formula to the entire range you want to compare.
The formula compares corresponding cells in Sheet1 and Sheet2 and displays the differences. For instance, if cell A1 in Sheet1 contains “Apple” and cell A1 in Sheet2 contains “Orange,” the formula in the new sheet will display “Sheet1:Apple vs Sheet2:Orange.”
3. Highlighting Differences Between Two Excel Sheets with Conditional Formatting
Conditional formatting can highlight cells with different values in two sheets, making it easier to spot discrepancies visually.
3.1 Applying Conditional Formatting
- Select the Range: In the worksheet where you want to highlight the differences, select all used cells by clicking the upper-left cell (usually A1) and pressing
Ctrl + Shift + End. - Create a New Rule: Go to the Home tab, in the Styles group, click Conditional Formatting > New Rule.
- Use a Formula: Select “Use a formula to determine which cells to format” and enter the following formula:
=A1<>Sheet2!A1Replace Sheet2 with the name of the other sheet you are comparing.
- Format the Cells: Click the Format button to choose a color or style to highlight the different cells. Click OK to apply the rule.
Cells with different values will be highlighted with the selected format.
3.2 Limitations of Formulas and Conditional Formatting
While formulas and conditional formatting are useful, they have limitations:
- Value Comparison Only: They only identify differences in values and do not compare formulas or cell formatting.
- Row and Column Sensitivity: They cannot identify added or deleted rows and columns. Adding or deleting a row/column in one sheet will mark subsequent rows/columns as differences.
- Sheet-Level Only: They operate on a sheet level and cannot detect structural differences at the workbook level, such as sheet additions or deletions.
4. Using the Compare and Merge Feature for Shared Workbooks
When multiple users collaborate on the same Excel workbook, the Compare and Merge feature is useful for viewing changes and comments from all users at once.
4.1 Preparing the Workbooks
- Share the Workbook: Before making the workbook available, share it by clicking the Share Workbook button on the Review tab, in the Changes group. Select “Allow changes by more than one user…” and click OK.
- Save Copies: Each user must save a copy of the shared workbook with a unique file name.
4.2 Enabling the Compare and Merge Workbooks Feature
This feature may not be displayed in Excel by default. To add it to the Quick Access Toolbar:
- Customize Quick Access Toolbar: Open the Quick Access drop-down menu and select More Commands.
- Choose Commands: In the Excel Options dialog box, select All Commands under “Choose commands from.”
- Add the Command: Scroll down to Compare and Merge Workbooks, select it, and click Add to move it to the right-hand section. Click OK.
4.3 Comparing and Merging Workbooks
- Open the Primary Version: Open the original shared workbook.
- Click Compare and Merge: Click the Compare and Merge Workbooks command on the Quick Access Toolbar.
- Select Copies: In the dialog box, select the copies of the shared workbook you want to merge. Hold the
Shiftkey to select multiple copies, and then click OK.
4.4 Reviewing the Changes
- Highlight Changes: To see all edits at a glance, go to the Review tab > Changes group and click Track Changes > Highlight Changes.
- Configure Highlighting: In the Highlight Changes dialog, select All in the When box, Everyone in the Who box, clear the Where box, select “Highlight changes on screen,” and click OK.
Excel highlights column letters and row numbers with differences in dark red. Edits from different users are marked with different colors. Hover over a cell to see who made the change.
