This makes it easier to compare the contents of the files line by line.

Limitations of “View Side by Side”:

• It only allows for visual comparison, which can be time-consuming and prone to errors.
• It doesn’t highlight or identify specific differences between the files.
• It’s not suitable for comparing large files or files with complex formulas.

2.2. Conditional Formatting

Conditional formatting can be used to highlight cells that meet certain criteria, such as differences in values or formulas. This can be helpful for identifying specific changes between two versions of a file.

How to use conditional formatting for comparison:

1. Open the two Excel files you want to compare.
2. In one of the files, select the range of cells you want to compare.
3. Go to the “Home” tab on the ribbon.
4. In the “Styles” group, click “Conditional Formatting.”
5. Choose “New Rule.”
6. In the “New Formatting Rule” dialog box, select “Use a formula to determine which cells to format.”
7. Enter a formula that compares the values in the selected range with the corresponding values in the other file. For example, if you want to highlight cells that are different, you can use the formula =A1<>'[OtherFile.xlsx]Sheet1'!A1, where A1 is the first cell in the selected range and [OtherFile.xlsx]Sheet1'!A1 is the corresponding cell in the other file.
8. Click “Format” to choose the formatting you want to apply to the cells that meet the criteria.
9. Click “OK” to create the rule.

Excel will highlight the cells in the selected range that meet the criteria specified in the formula.

Limitations of conditional formatting:

• It can be time-consuming to set up, especially for large files or complex comparisons.
• It only highlights differences based on specific criteria, such as values or formulas.
• It doesn’t provide a comprehensive comparison report.

2.3. The IF Function

The IF function can be used to compare values in two cells and return a specific result based on whether they are equal or not. This can be helpful for identifying differences in specific cells or ranges.

How to use the IF function for comparison:

1. Open the two Excel files you want to compare.
2. In a new column, enter the IF function to compare the values in the corresponding cells in the two files. For example, if you want to return “Different” if the values are not equal and “Same” if they are equal, you can use the formula =IF(A1='[OtherFile.xlsx]Sheet1'!A1,"Same","Different"), where A1 is the cell in the first file and [OtherFile.xlsx]Sheet1'!A1 is the corresponding cell in the other file.
3. Copy the formula down to compare all the cells in the range.

Excel will return “Same” or “Different” in the new column, indicating whether the values in the corresponding cells are equal or not.

Limitations of the IF function:

    Set wb2 = Workbooks.Open("C:PathToFile2.xlsx")
    Set ws1 = wb1.Sheets("Sheet1")
    Set ws2 = wb2.Sheets("Sheet1")

    ' Get the last row and column
    lastRow = ws1.Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row
    lastCol = ws1.Cells.Find("*", SearchOrder:=xlByColumns, SearchDirection:=xlPrevious).Column

    ' Loop through each cell and compare values
    For i = 1 To lastRow
        For j = 1 To lastCol
            Set cell1 = ws1.Cells(i, j)
            Set cell2 = ws2.Cells(i, j)

            If cell1.Value <> cell2.Value Then
                Debug.Print "Difference found at Row: " & i & ", Column: " & j
                Debug.Print "File 1: " & cell1.Value
                Debug.Print "File 2: " & cell2.Value
