Just discovered a nice Opensource spreadsheet program: gnumeric.
Seems more lightweight than openoffice, e.g. memory footprint was 20MB. Supports many file formats, Excel 2003 like GUI.
I'll try to use it (Version 1.9.12 on windows XP) to replace Excel..
Issues so far (2009.10.13):
- If one clicks on a cells and types, nothing happens.
One must double click: this takes time and means un-learning an old Excel habit..
- When running, does not appear in my Taskbar!
- Cannot chage interface language (I installed french but would have like to switch to english..)
