    Dim wb1 As Workbook, wb2 As Workbook
    Dim ws1 As Worksheet, ws2 As Worksheet
    Dim cell1 As Range, cell2 As Range
    Dim lastRow As Long, lastCol As Long
    Dim i As Long, j As Long

    ' Set the workbooks and worksheets to compare
    Set wb1 = Workbooks.Open("C:PathToFirstWorkbook.xlsx")
    Set wb2 = Workbooks.Open("C:PathToSecondWorkbook.xlsx")
    Set ws1 = wb1.Sheets("Sheet1")
    Set ws2 = wb2.Sheets("Sheet1")

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

    ' Loop through each cell in the first worksheet
    For i = 1 To lastRow
        For j = 1 To lastCol
            ' Set the cell objects
            Set cell1 = ws1.Cells(i, j)
            Set cell2 = ws2.Cells(i, j)

            ' Compare the cell 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

    ' Close the workbooks
    wb1.Close SaveChanges:=True
    wb2.Close SaveChanges:=True

    MsgBox "Excel comparison complete."

End Sub

This script opens two Excel workbooks, compares the values in each cell, and highlights the differences in red.
