4. Understanding the Comparison Results

The results of the comparison are presented in a detailed format, allowing you to quickly identify and understand the differences between the two files.

4.1. Interpreting Color Codes and Highlighting

The color codes and highlighting used in Spreadsheet Compare are crucial for understanding the types of changes that have been made.

Green Fill: Indicates that an entered value (non-formula cell) has changed.
Blue-Green Fill: Indicates that a calculated value has changed.
Other Colors: May indicate differences in formatting, formulas, or other attributes.

4.2. Navigating Through Worksheets

When comparing workbooks with multiple worksheets, use the navigation buttons to move between sheets and review the differences in each. Even hidden worksheets are compared and displayed in the results, ensuring a thorough analysis.

4.3. Filtering and Sorting Results

Spreadsheet Compare allows you to filter and sort the comparison results to focus on specific types of changes. For example, you can filter the results to show only changes in formulas or formatting. Sorting can help you organize the changes by cell location or type of modification.

4.4. Example Scenario

Consider a scenario where you are comparing two versions of a sales report. The earlier version has preliminary data for Q4, while the latest version contains final numbers. Spreadsheet Compare highlights the changes in the Q4 cells (E2:E5) with a green fill, indicating that the entered values have changed. Additionally, the calculated results in the YTD column (F2:F4 and E6:F6) have a blue-green fill, showing that the calculated values have also changed due to the updated data.

In this example, cell F5 also changed, but the tool reveals that the formula in the earlier version was incorrect. The updated version corrects the formula from =SUM(B5:D5) to =SUM(B5:E5), providing valuable insight into both data and formula discrepancies.
