12.1.1 Example VBA Code

Here’s a simple example of VBA code that compares two worksheets and highlights the differences:

Sub CompareSheets()

    Dim ws1 As Worksheet, ws2 As Worksheet
    Dim cell1 As Range, cell2 As Range
    Dim lastRow As Long, lastCol As Long

    ' Set the worksheets to compare
    Set ws1 = ThisWorkbook.Sheets("Sheet1")
    Set ws2 = ThisWorkbook.Sheets("Sheet2")

    ' 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
    For i = 1 To lastRow
        For j = 1 To lastCol
            ' Set the cells to compare
            Set cell1 = ws1.Cells(i, j)
            Set cell2 = ws2.Cells(i, j)

            ' Compare the values
            If cell1.Value <> cell2.Value Then
                ' Highlight the differences
                cell1.Interior.Color = RGB(255, 0, 0) ' Red
                cell2.Interior.Color = RGB(255, 0, 0) ' Red
            End If
        Next j
    Next i

    MsgBox "Comparison Complete!"

End Sub

This code compares “Sheet1” and “Sheet2” in the active workbook and highlights any differences in red.

12.2 Using Power Query for Data Comparison

Power Query is a powerful data transformation and analysis tool that can be used to compare data from multiple sources, including Excel files. With Power Query, you can import data from two Excel files, merge the data based on common columns, and identify differences using custom formulas.
