in reply to Open a file in append mode

What kind of object is stored in $worksheet and what does the documentation of the relevant module say about its ->write method?

You cannot simply mix and match modules that contain "Spreadsheet" or "XLS" in their name and hope that Perl will figure out how you want to use them.

    Then is there any module to read & write an excel sheet without losing my previous data. (append mode)

        Spreadsheet::ParseExcel::SaveParser working amazingly. Somebody suggested Win32::OLE. Which is more effective and which one is simpler???

        Before you said that dont mingle modules. In this  Spreadsheet::ParseExcel::SaveParser i cant find max_rows & max_col which is available in other modules. As per my requirement I need to insert a row which consists of 11 columns in the end of the sheet. In this Saveparser how to find last row
