1. Create Excel file in 2010 and save as 97-2003 format
2. Modify cell like this:
        Try
            Dim WorkBook As New ExcelLibrary.SpreadSheet.Workbook
            WorkBook = ExcelLibrary.SpreadSheet.Workbook.Load("C:\Users\Archie\Documents\TempTest2.xls")
            WorkBook.Worksheets(0).Cells(0, 0).Value = "added text"
            WorkBook.Save("C:\Users\Archie\Documents\TempTest3.xls")
        Catch ex As Exception
            MsgBox(ex.Message)
        End Try

3. New sheet (TempTest3.xls) is not readable in Excel
