in reply to Save as .xlsm file

Unless your Excel 2003 knows how to save the spreadsheet data in .xslm format you must have Excel 2007 installed.

I had a quick check on CPAN and it seems there is no module available that allows you to save in .xslm format.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
