Gnumeric is a good, lightweight spreadsheet that, with AbiWord and GNOME-DB form the Gnome office suite.
It's fully compatible with Excel spreadsheets, and works far more similarly than does openoffice.
I think that Gnumeric would make a nice lightweight alternative to Openoffice Calc.
I think there is a portable version floating around the forums here somewhere, i can't seem to find the link right now, but use the Search in the top right corner for Gnumeric Portable

what happened to this project?
I downloaded it awhile back and use it sometimes, and I was going to tell someone else where to get it and all traces of the program are gone. tanisthalon's site is down and I can't seem to find it hear cause all links lead to his site. https://portableapps.com/node/3956 is where I got it from before. there were talks in the posts there that people were going to mirror it. did anyone?

http://www.portablefreeware.com This post https://portableapps.com/node/9087 mentions
a version of Gnumeric posted there.
Seems that the thread for the out of date portable version here has been locked.
Portable OOo is nice, but Gnumeric would be great for older PC's.
