5. Step-by-Step Guide: Excel Compare Two Workbooks Using Conditional Formatting

Conditional formatting is a powerful feature in Excel that allows you to highlight differences between two workbooks. This method is useful for visually identifying discrepancies and errors. Here’s a step-by-step guide on how to use conditional formatting to compare two Excel workbooks:

5.1. Open Both Workbooks

• Start by opening both Excel workbooks that you want to compare. Ensure that the workbooks are arranged in a way that allows you to easily switch between them.

5.2. Select the Data Range in the First Workbook

• In the first workbook, select the range of cells that you want to compare with the corresponding cells in the second workbook.

5.3. Open Conditional Formatting

• Go to the Home tab in the Excel ribbon.
• In the Styles group, click on Conditional Formatting.
• From the dropdown menu, select New Rule.

5.4. Create a New Formatting Rule

• In the New Formatting Rule dialog box, select the rule type Use a formula to determine which cells to format.

5.5. Enter the Comparison Formula

• In the Format values where this formula is true field, enter a formula that compares the selected cells in the first workbook with the corresponding cells in the second workbook.
• For example, if you want to compare cell A1 in the first workbook with cell A1 in the second workbook, the formula would be: =$A1<>'[Workbook2.xlsx]Sheet1'!$A1
  • Replace Workbook2.xlsx with the actual name of the second workbook.
  • Replace Sheet1 with the name of the sheet you want to compare in the second workbook.
  • The <> operator means “not equal to.”

5.6. Set the Formatting Options

• Click the Format button to specify how you want the differences to be highlighted.
• In the Format Cells dialog box, you can set the font, border, and fill options.
• For example, you can choose to fill the cells with a specific color (e.g., red) to indicate differences.
• Click OK to save the formatting options.

5.7. Apply the Rule

• Click OK in the New Formatting Rule dialog box to apply the conditional formatting rule to the selected range of cells.

5.8. Review the Results

• Excel will now highlight the cells in the first workbook that are different from the corresponding cells in the second workbook.

5.9. Repeat for Additional Ranges

• If you want to compare additional ranges of cells, repeat the steps above for each range.

5.10. Save the Workbook

• Save the first workbook to preserve the conditional formatting rules.

5.11. Tips and Considerations

• Absolute and Relative References: Use absolute references ($A$1) if you want the formula to always refer to the same cell. Use relative references (A1) if you want the formula to adjust based on the position of the cell.
• Handling Errors: If the workbooks contain errors (e.g., #N/A), the comparison formula may also return an error. Use the IFERROR function to handle errors gracefully.
• Performance: Applying conditional formatting to large datasets can impact performance. Consider using this method for smaller ranges of cells.
• Complexity: For complex comparisons, consider using more advanced techniques such as VBA or third-party tools.
