    Set Sheet2 = ThisWorkbook.Sheets("Sheet2")

    Set Range1 = Sheet1.UsedRange
    Set Range2 = Sheet2.UsedRange

    Application.ScreenUpdating = False 'Turn off screen updating for faster execution

    For Each Cell In Range1
        If Cell.Value <> Sheet2.Cells(Cell.Row, Cell.Column).Value Then
            Cell.Interior.Color = RGB(255, 0, 0) 'Highlight in red
            Sheet2.Cells(Cell.Row, Cell.Column).Interior.Color = RGB(255, 0, 0)
        Else
            Cell.Interior.Color = xlNone 'Remove highlight if values are the same
            Sheet2.Cells(Cell.Row, Cell.Column).Interior.Color = xlNone
        End If
    Next Cell

    Application.ScreenUpdating = True 'Turn on screen updating
