2. Simple Visual Comparison: “View Side by Side”

The “View Side by Side” feature in Excel allows you to visually compare two sheets. This method is best suited for smaller datasets where discrepancies are easily noticeable.

2.1. Opening Excel Windows Side by Side

To open two Excel files side by side:

Open both Excel workbooks that you want to compare.
Go to the View tab on the ribbon.
In the Window group, click the View Side by Side button.

This will arrange the two workbooks side by side on your screen, allowing you to scroll and compare them visually.

2.2. Arranging Windows Vertically

By default, Excel displays the windows horizontally. To arrange them vertically:

Click the Arrange All button in the Window group on the View tab.
Select the Vertical option.
Click OK.

This will display the Excel windows in a vertical arrangement, which some users may find more convenient.

2.3. Synchronous Scrolling

To scroll through both worksheets simultaneously:

Ensure that the Synchronous Scrolling option is turned on.
This option is located in the Window group on the View tab, directly under the View Side by Side button.

With Synchronous Scrolling enabled, scrolling in one window will automatically scroll the other, making it easier to compare data row by row.

2.4. Comparing Multiple Excel Windows

To compare more than two Excel files:

Open all the workbooks you want to compare.
Click the View Side by Side button.
In the Compare Side by Side dialog box, select the files you want to display together with the active workbook.

Alternatively, you can click the Arrange All button and choose your preferred arrangement (tiled, horizontal, vertical, or cascade).

2.5. Comparing Two Sheets in the Same Workbook

To compare two sheets within the same workbook:

Open the 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 different window.
Enable View Side by Side mode.
Select the first sheet in one window and the second sheet in the other window.

3. Formula-Based Comparison for Value Differences

Using Excel formulas, you can create a difference report to identify cells with different values. This method is useful for pinpointing exact discrepancies between two sheets.

3.1. Creating a Difference Report

Open a new, empty sheet in your Excel workbook.
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 (the small square at the bottom-right of the cell).

3.2. Understanding the Formula

Sheet1!A1 and Sheet2!A1 refer to cell A1 in Sheet1 and Sheet2, respectively.
The <> operator checks if the values in the two cells are different.
If the values are different, the formula returns a text string indicating the values from both sheets.
If the values are the same, the formula returns an empty string (“”).

3.3. Limitations

While this method is straightforward, it has limitations:

It only compares values and does not compare formulas or formatting.
Dates are displayed as serial numbers, which can be inconvenient.
It does not identify added or deleted rows and columns.

4. Conditional Formatting for Highlighting Differences

Conditional formatting can be used to highlight cells with different values in two sheets. This visual aid makes it easier to quickly identify discrepancies.

4.1. Applying Conditional Formatting

In the worksheet where you want to highlight differences, select all used cells. Click the upper-left cell (usually A1) and press Ctrl + Shift + End to extend the selection to the last used cell.
Go to the Home tab on the ribbon.
In the Styles group, click Conditional Formatting > New Rule.
Select Use a formula to determine which cells to format.
Enter the following formula:

=A1<>Sheet2!A1
Click the Format button to choose the formatting style (e.g., fill color, font style).
Click OK to apply the rule.

4.2. Understanding the Formula

A1 refers to the first cell in your selection.
Sheet2!A1 refers to the corresponding cell in the second sheet.
The formula checks if the values in the two cells are different. If they are, the conditional formatting is applied.

4.3. Limitations

Like the formula-based method, conditional formatting has limitations:

It only finds differences in values and does not compare formulas or formatting.
It cannot identify added or deleted rows and columns.
It works on a sheet level but cannot detect workbook-level structural differences.

5. Compare and Merge Copies of a Shared Workbook

Excel’s “Compare and Merge” feature is designed for merging different versions of a shared workbook. This is especially useful when multiple users collaborate on the same file.

5.1. Preparing the Workbook

Before using the “Compare and Merge” feature:

Share the Excel workbook by clicking 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 user must save a copy of the shared workbook with a unique file name.

5.2. Enabling the “Compare and Merge Workbooks” Feature

The “Compare and Merge Workbooks” feature is not displayed in Excel 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.
Scroll down to Compare and Merge Workbooks, select it, and click the Add button.
Click OK.

5.3. Comparing and Merging Workbooks

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 the copies of the shared workbook that you want to merge. Hold the Shift key to select multiple copies.
Click OK.

Excel will merge the changes from each copy into a single workbook.

5.4. Reviewing the Changes

To see all edits by different users:

Switch to the Review tab > 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 with differences in dark red. Cell-level edits are marked with different colors to indicate who made the change.

5.5. Limitations

The “Compare and Merge Workbooks” feature is limited to merging copies of the same shared workbook. It cannot be used to compare different Excel files.
