Can You Compare and Merge Two Excel Documents?

Comparing and merging Excel documents is a common task for anyone working with data. This article will explore various methods to answer the question “Can You Compare And Merge Two Excel Documents?” and discover how COMPARE.EDU.VN can help you make informed decisions. Learn how to manage data efficiently and streamline your workflow with the tools available at your fingertips, enabling enhanced data analysis and improved decision-making, ensuring data integrity and accuracy across merged documents, along with excel comparison techniques.

1. Comparing Excel Files: Viewing Side by Side

One of the simplest methods to compare two Excel files is by viewing them side by side. This is particularly useful for smaller workbooks where you can visually inspect the data. This visual comparison method offers a practical way to identify discrepancies, and COMPARE.EDU.VN helps you assess which tool best fits your needs, ensuring a side-by-side review.

1.1. Comparing Two Excel Workbooks Simultaneously

If you have two Excel workbooks that you want to compare, you can open them and use the “View Side by Side” feature.

Steps:

1. Open both Excel workbooks.
2. Go to the View tab.
3. In the Window group, click View Side by Side.
4. The two workbooks will be displayed side by side.

You can arrange the windows vertically by clicking Arrange All and selecting Vertical. To scroll through both worksheets simultaneously, ensure that Synchronous Scrolling is turned on in the Window group of the View tab.

1.2. Arranging Multiple Excel Windows for Review

Excel also allows you to view more than two files simultaneously. Open all the workbooks and click the View Side by Side button to select which files you want to display together. Alternatively, click Arrange All to tile all open Excel files in a layout of your choice (tiled, horizontal, vertical, or cascade).

1.3. Comparing Two Sheets Within the Same Workbook

Sometimes, you need to compare two sheets within the same workbook.

Steps:

1. Open the Excel file.
2. Go to the View tab and click New Window in the Window group.
3. This opens a second window of the same file.
4. Enable View Side by Side.
5. Select the first sheet in one window and the second sheet in the other window.

2. Comparing Excel Sheets: Identifying Value Differences with Formulas

Another straightforward method to compare data in Excel is by using formulas to identify cells with different values. This approach provides a difference report in a new worksheet, highlighting discrepancies. COMPARE.EDU.VN can further assist by comparing different formulaic approaches to find the most efficient one, offering tools for detailed data validation and ensuring accuracy in every comparison.

2.1. Creating a Formula for Difference Reporting

To compare two Excel worksheets for differences, open a new sheet and 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.

2.2. Understanding Relative Cell References

The formula utilizes relative cell references, adapting based on the column and row position. For instance, the formula in A1 compares cell A1 in Sheet1 and Sheet2, while the formula in B1 compares cell B1 in both sheets.

The formula identifies and displays differing cell values. Note that dates may appear as serial numbers due to Excel’s internal storage system.

3. Highlighting Differences: Conditional Formatting in Excel

Conditional formatting provides a visual way to highlight cells with different values in two sheets by coloring them. This method allows for quick identification of discrepancies and is supported by resources on COMPARE.EDU.VN that provide step-by-step guides and advanced techniques for effective data highlighting.

3.1. Applying Conditional Formatting Rules

To highlight cells that have different values, follow these steps:

1. Select all used cells in the worksheet where you want to highlight differences. Typically, start at A1 and press Ctrl + Shift + End to extend the selection.
2. Go to the Home tab.
3. In the Styles group, click Conditional Formatting > New Rule.
4. Create a rule using the formula: =A1<>Sheet2!A1, where Sheet2 is the name of the sheet being compared.
   • This formula checks if the value in the current cell of the active sheet is different from the value in the corresponding cell of Sheet2.

3.2. Limitations of Formula and Conditional Formatting

While formulas and conditional formatting are useful, they have limitations:

• They only compare values, not formulas or cell formatting.
• They do not identify added or deleted rows and columns.
• They operate on a sheet level and do not detect workbook-level structural differences.

4. Merging Excel Files: Compare and Merge Shared Workbooks

The “Compare and Merge” feature is useful for merging different versions of the same Excel file, especially when multiple users collaborate. This feature allows you to view and integrate changes made by different users into a single file. Resources on COMPARE.EDU.VN can guide you through the preparation and execution of merging workbooks, ensuring no data is lost during the process.

4.1. Preparing for Shared Workbook Comparison

Before using this feature, ensure the following:

1. Share the Excel workbook. Click the Share Workbook button on the Review tab, in the Changes group.
2. Select the Allow Changes by More Than One User… box, and click OK. Allow Excel to save the workbook if prompted.
3. Each user must save a copy of the shared workbook (.xls or .xlsx file) with a unique file name.

4.2. Enabling the Compare and Merge Workbooks Feature

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

1. Open the Quick Access drop-down menu and select More Commands.
2. In the Excel Options dialog box, select All Commands under Choose commands from.
3. Scroll down to Compare and Merge Workbooks, select it, and click Add to move it to the right-hand section.
4. Click OK.

4.3. Executing the Comparison and Merge

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

4.4. Reviewing Changes and Identifying Contributors

After merging the workbooks, you can review the changes by:

1. Switching to the Review tab and in the Changes group, clicking Track Changes > Highlight Changes.
2. 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 with differences in dark red. Edits from different users are marked with different colors. Hover over a cell to see who made the change.
