in reply to Need help in reading csv files >1GB for converting into xlsx files in Solaris 10 - Perl v-5.8.4

Have a look at "Excel Hacks" by David & Raina Hawley (O'Reilly), in particular Hack #14 (First Edition) or Hack #15 (Second Edition) titled "Reduce Workbook Bloat".

P.S. Use Google to search for 'filetype:pdf excel hacks'

Searched for donuts and crumpit. Found content instead.
