has anybody found a library that works well with large spreadsheets?
I’ve tried apache’s POI but it fails miserably working with large files – both reading and writing. It uses massive amounts of memory leaving you needing a supercomputer to parse or create a 20+mb spreadsheet.
Surely there is a more memory efficient way and someone has written it?!
at time of posting, there is no pure java scalable solution for reading and writing large excel files.
