2. Native Excel 2007 Features for File Comparison

Excel 2007 offers some built-in features that can be used for basic file comparison. While these features may not be as robust as dedicated comparison tools, they can be useful for simple tasks.

2.1 Viewing Files Side-by-Side

The View Side by Side mode in Excel 2007 allows you to arrange two Excel windows next to each other, making it easier to visually compare the contents.

2.1.1 How to Activate View Side by Side

To activate View Side by Side mode:

Open both Excel files you want to compare.
Go to the View tab in the Excel ribbon.
In the Window group, click the View Side by Side button.
Excel will arrange the two files horizontally or vertically, depending on your settings.

2.1.2 Synchronous Scrolling

To scroll through both worksheets simultaneously, enable the Synchronous Scrolling feature, also found on the View tab, in the Window group. This ensures that both files scroll together, allowing you to compare data row-by-row.

2.1.3 Limitations of View Side by Side

While View Side by Side is useful for a quick visual comparison, it has limitations:

Manual Comparison: It requires manual visual inspection, which can be time-consuming and error-prone for large datasets.
No Automated Highlighting: It doesn’t automatically highlight differences between the files.
Not Suitable for Complex Comparisons: It’s not ideal for comparing files with significant structural differences or complex formulas.

2.2 Using Formulas for Difference Reports

You can use Excel formulas to create a difference report, which identifies cells with different values between two sheets.

2.2.1 Creating a Difference Report

To create a difference report:

Open a new, empty sheet in Excel.
Enter the following formula in cell A1:

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

Copy the formula down and to the right by dragging the fill handle.

This formula compares the value in cell A1 of Sheet1 with the value in cell A1 of Sheet2. If the values are different, it displays the values from both sheets; otherwise, it leaves the cell blank.

2.2.2 Limitations of Formula-Based Comparison

This method also has several limitations:

Value Comparison Only: It only compares values and doesn’t identify differences in formulas or formatting.
Structural Issues: It doesn’t handle added or deleted rows and columns well.
Date Formatting: Dates may be displayed as serial numbers, making it difficult to compare them.

2.3 Conditional Formatting for Highlighting Differences

Conditional formatting can be used to highlight cells with different values between two sheets, providing a visual indication of discrepancies.

2.3.1 Applying Conditional Formatting

To apply conditional formatting:

Select all used cells in the worksheet where you want to highlight differences.
Go to the Home tab, 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 Format to choose the formatting style (e.g., fill color) for the different cells.
Click OK to apply the rule.

2.3.2 Limitations of Conditional Formatting

Conditional formatting offers some benefits, but it also has limitations:

Value-Based: It primarily focuses on value differences and doesn’t identify differences in formulas or formatting.
Structural Changes: Added or deleted rows and columns can disrupt the comparison.
Complexity: Setting up conditional formatting rules can be complex for users unfamiliar with Excel formulas.
