Compare Data in 2 Excel Sheets: Essential Techniques for Deep Analysis

When working with data, especially in environments reliant on spreadsheets, the need to Compare Data In 2 Excel Sheets arises frequently. Whether you are auditing financial records, reconciling inventory lists, or simply tracking changes across different versions of a report, effectively comparing Excel sheets is crucial. Identifying discrepancies, understanding modifications, and ensuring data integrity are all essential for informed decision-making and operational accuracy.

Imagine you have two versions of a sales report, each residing in a separate Excel sheet. Quickly discerning which products have shifted in performance, pinpointing new entries, or understanding pricing adjustments becomes paramount. Beyond simple reports, comparing Excel sheets can be vital for detecting broken links within workbooks, uncovering duplicate entries that skew analysis, identifying inconsistencies in formulas that lead to erroneous calculations, or flagging formatting variations that impact readability and presentation.

This guide explores a comprehensive range of methods to compare data in 2 Excel sheets, moving from straightforward visual techniques to more sophisticated, automated solutions. We will delve into native Excel functionalities and also introduce powerful third-party tools designed to streamline and enhance your data comparison tasks. By mastering these techniques, you’ll significantly improve your efficiency and accuracy when working with comparative data in Excel.

1. Side-by-Side Viewing: A Visual Approach to Compare Excel Sheets

For datasets that are manageable in size and when a quick, visual check is sufficient, leveraging Excel’s “View Side by Side” mode offers a remarkably simple solution to compare data in 2 Excel sheets. This feature allows you to arrange two Excel windows directly next to each other, facilitating a direct visual scan for differences. This method is applicable whether you’re comparing two distinct Excel workbooks or two different sheets within the same workbook.

1.1. How to Compare Two Excel Workbooks in Side-by-Side View

Consider a scenario where you need to compare data in 2 Excel sheets representing sales figures from two different quarters. Using the side-by-side view allows for an immediate visual assessment of performance variations.

Here’s how to set up this view:

Begin by opening both Excel workbooks that you intend to compare.
Navigate to the View tab on the Excel ribbon. In the Window group, locate and click the View Side by Side button. With a single click, Excel will automatically position the two open workbooks adjacent to each other.

Initially, Excel typically arranges the windows horizontally, placing one above the other.

If a vertical arrangement is more suitable for your comparison needs, perhaps for wider datasets, you can easily switch the layout. Click the Arrange All button, also located in the Window group under the View tab. In the Arrange Windows dialog box, select the Vertical option and click OK.

Alt text: Vertically arranged Excel windows showing two different spreadsheets side-by-side, enhancing visual comparison of data in two excel sheets.

This will reorganize your Excel windows, presenting them in a side-by-side vertical format, as illustrated above, which can be particularly effective for comparing columns of data across two sheets.

To enhance the comparison process, especially when you want to scroll through both sheets simultaneously to examine corresponding rows, ensure that Synchronous Scrolling is enabled. This feature is usually activated automatically when you engage the “View Side by Side” mode. You can verify or toggle this setting in the Window group of the View tab, directly beneath the “View Side by Side” button. When activated, scrolling in one window will cause the other to scroll in tandem, keeping corresponding rows aligned for easier comparison.

Alt text: Synchronous scrolling option highlighted in Excel, illustrating its function to simultaneously scroll two excel sheets for parallel data comparison.

For a more detailed guide on utilizing this feature, refer to resources specifically dedicated to viewing Excel workbooks side by side.

1.2. Managing Multiple Excel Windows for Comparison

Extending beyond just two files, Excel allows you to compare data in 2 excel sheets even when you need to view more than two Excel files simultaneously. If you have several workbooks open that you need to compare, clicking the View Side by Side button will initiate the Compare Side by Side dialog box. This dialog will list all currently open workbooks, allowing you to select which files should be displayed alongside the active workbook.

Alt text: Dialog box in Excel showing options to select multiple workbooks for side-by-side comparison, useful when comparing data across several excel sheets.

For a broader overview of all open Excel files at once, the Arrange All button is invaluable. Located in the same Window group on the View tab, clicking “Arrange All” presents several layout options: tiled, horizontal, vertical, or cascade. Choose the arrangement that best suits your comparative task and the number of files you’re working with.

1.3. Comparing Sheets Within the Same Excel Workbook

Often, the need to compare data in 2 Excel sheets arises when the sheets are within the same workbook. To view two sheets from the same workbook side by side, follow these steps:

Open the Excel workbook containing the sheets you wish to compare. Then, go to the View tab and in the Window group, click New Window.
This action opens a second window displaying the same Excel file. Essentially, you now have two independent windows showing the same workbook.
Activate the View Side by Side mode by clicking the corresponding button on the ribbon in either of the windows.
In one of the Excel windows, navigate to and select the first sheet you want to compare. In the other window, select the second sheet.

By following these steps, you can effectively view and compare data in 2 Excel sheets that reside within the same Excel workbook, making visual comparison straightforward and efficient.

2. Formula-Based Comparison: Spotting Value Differences in Excel Sheets

When visual inspection is insufficient or when you need a more structured approach to compare data in 2 Excel sheets, using Excel formulas provides a powerful method to programmatically identify differences in values. This technique is particularly useful for generating a difference report directly within Excel.

To implement a formula-based comparison, you can create a new, empty worksheet that will serve as your difference report. In cell A1 of this new sheet, enter the following formula:

=IF(Sheet1!A1<>Sheet2!A1, "Sheet1:"&Sheet1!A1&" vs Sheet2:"&Sheet2!A1, "")

After entering this formula in cell A1, you need to apply it across the range of cells you wish to compare. You can easily do this by using the fill handle—the small square at the bottom-right corner of the selected cell. Drag the fill handle down and to the right to cover the entire range that corresponds to the data in your original sheets. This action automatically copies the formula, adjusting cell references relative to their new positions.

The use of relative cell references in the formula is crucial. It ensures that as you copy the formula across cells, it dynamically adjusts to compare corresponding cells in Sheet1 and Sheet2. For instance, the formula in cell B1 will compare cell B1 in both Sheet1 and Sheet2, and so on.

The result of this formula is a difference report that highlights cells where the values differ between the two sheets. Where values are identical, the cell in the report remains blank. Where differences exist, the report cell will display a text string indicating the values from both sheets that are different.

Alt text: Excel sheet showing a formula-based comparison report, highlighting value differences between two excel sheets, with discrepancies clearly noted in designated cells.

As illustrated above, the formula effectively identifies cells with differing values and presents these differences in the corresponding cells of the report sheet. It’s important to note, however, that dates in this difference report (like cell C4 in the example) are displayed as serial numbers—Excel’s internal representation of dates. This representation, while accurate, can be less intuitive for quickly analyzing date discrepancies. This method primarily focuses on value comparison and does not extend to comparing formulas or formatting.

3. Conditional Formatting: Visually Highlighting Differences in Excel Sheets

To enhance visual analysis when you compare data in 2 Excel sheets, conditional formatting offers an excellent way to automatically highlight cells that contain different values. This method allows you to apply color coding to discrepancies, making them instantly recognizable.

Here’s how to use conditional formatting to highlight differences:

First, select the worksheet where you want the differences to be highlighted. Choose the entire used range of cells in this sheet. A quick way to do this is by clicking the top-left cell of your data range (usually A1), and then pressing Ctrl + Shift + End to extend the selection to the last used cell.
Navigate to the Home tab on the Excel ribbon. In the Styles group, click on Conditional Formatting, then select New Rule… from the dropdown menu.
In the New Formatting Rule dialog box, choose Use a formula to determine which cells to format. In the formula box, enter the following formula:
```
=A1<>Sheet2!A1
```
Ensure you replace Sheet2 with the actual name of the second sheet you are comparing against.
Click the Format… button to specify how you want the differing cells to be highlighted. Choose your preferred formatting style, such as fill color, font style, or border. Once you have set your formatting preferences, click OK to close the Format Cells dialog, and then click OK again to apply the conditional formatting rule.

As a result, all cells in your selected range that have values different from their corresponding cells in Sheet2 will be highlighted with the color and style you specified.

Alt text: Conditional formatting rule setup in Excel, showing the formula to compare values across two excel sheets and the formatting options to highlight differences.

If you are new to conditional formatting in Excel, detailed guidance can be found in tutorials on Excel conditional formatting based on another cell value.

While formulas and conditional formatting are user-friendly for compare data in 2 excel sheets based on values, they have limitations for comprehensive comparisons:

Value-centric: They only compare cell values and do not account for differences in formulas or cell formatting.
Structural Insensitivity: They cannot detect structural changes like added or deleted rows and columns. If rows or columns are added or removed in one sheet, subsequent row or column comparisons become misaligned, leading to inaccurate difference identification.
Sheet-Level Focus: These methods operate at the sheet level and cannot identify workbook-level structural differences, such as the addition or deletion of entire sheets.

For more in-depth comparisons that address these limitations, consider exploring more advanced Excel features or specialized third-party tools.

4. Compare and Merge Shared Workbooks: Excel’s Built-in Feature for Collaborative Changes

When collaboration is involved and multiple users are working on different copies of the same Excel workbook, Excel’s Compare and Merge Workbooks feature becomes invaluable. This built-in functionality is specifically designed to consolidate changes made by different users into a single primary workbook. It is particularly useful in scenarios where a shared workbook has been distributed, edited by various team members, and needs to be brought back together.

To effectively use the “Compare and Merge” feature, certain preparatory steps are essential:

Share the Workbook: Before distributing the workbook for editing, it must be set up as a shared workbook. To do this, click on the Review tab in Excel, then in the Changes group, click Share Workbook. In the Share Workbook dialog box, ensure the checkbox “Allow changes by more than one user at the same time. This also allows workbook merging” is selected, and click OK. If prompted to save the workbook, allow Excel to do so. Note that enabling the Track Changes feature automatically shares the workbook.
Save Copies with Unique Names: Each person who edits the shared workbook must save their copy with a unique filename. It is crucial that they save it as either an .xls or .xlsx file to ensure compatibility with the merge feature.

Once these preparations are complete, you are ready to use the “Compare and Merge Workbooks” feature to consolidate changes from the various copies.

4.1. Enabling the Compare and Merge Workbooks Command

Although the Compare and Merge Workbooks feature is available in Excel versions from 2010 through Microsoft 365, it is not readily accessible on the Excel ribbon by default. You need to add it to either the Quick Access Toolbar or the ribbon to use it. Here’s how to add it to the Quick Access Toolbar:

Click the dropdown arrow at the end of the Quick Access Toolbar (usually located at the very top left of the Excel window). Select More Commands… from the dropdown menu.
In the Excel Options dialog box, on the left side, choose Quick Access Toolbar. Then, under “Choose commands from,” select All Commands from the dropdown list.
Scroll through the list of commands to find Compare and Merge Workbooks. Select it and click the Add >> button to move it to the right-hand section, which lists the commands currently on your Quick Access Toolbar.

Open the primary version of the shared workbook—this is the workbook into which you want to merge all the changes.
Click the Compare and Merge Workbooks command that you added to the Quick Access Toolbar.
A dialog box will appear, prompting you to select the copies of the shared workbook that you want to merge into the primary workbook. You can select multiple copies by holding down the Shift key while clicking on the filenames. After selecting all relevant copies, click OK.

Alt text: Dialog box prompting selection of workbook copies for merging, step in consolidating changes from multiple users in excel sheets.

Excel will then automatically merge the changes from each selected copy into the primary workbook.

4.3. Reviewing Merged Changes

After merging, it’s crucial to review the changes to understand what modifications were made by different users. Excel provides tools to easily highlight and examine these changes:

Go to the Review tab on the ribbon, and in the Changes group, click Track Changes, then select Highlight Changes… from the dropdown menu.
In the Highlight Changes dialog box, configure the settings to best review the changes:
- In the When dropdown, select All to see all changes made.
- In the Who dropdown, select Everyone to review changes from all users.
- Ensure the Where box is cleared to apply the highlighting across the entire workbook.
- Check the box “Highlight changes on screen”.
- Click OK.

Alt text: Highlight Changes dialog box in Excel, configured to show all changes by everyone on screen, facilitating review of merged changes in excel sheets.

Excel will visually indicate the changes: column letters and row numbers with differences will be highlighted in dark red. At the cell level, edits from different users are marked with different colors. To identify who made a specific change, simply hover your mouse over a highlighted cell, and a tooltip will appear showing the user and the details of the edit.

Important Note: The Compare and Merge Workbooks command is specifically designed for merging copies of a shared workbook. It will not work if you are trying to merge different, unrelated Excel files. Ensure that the workbooks you are attempting to merge are indeed copies of the same originally shared file. If the command appears greyed out, double-check that you are working with a shared workbook and its copies.
