Spreadsheet program

Hi all, I don't know if this has been mentioned, but a quick search of the forum revealed no results. I just read Knightfly's post on the xls room mode viewer and I use a shareware spreadsheet program that allows me to impots .xls files without laying out any cash. The program is called 602Tab, it's part of the 602Suite, a set of office tools that sortof mimic the funcionality of Microsoft Office. I believe you can download a mostly functional version here: http://download.com.com/3000-2064-10028076.html Like I said, maybe everyone already knows about it, but if not, it's been really helpful for me 'cause I don't have a copy of office.

I just use OpenOffice. I opened up the correct Helmholtz spreadsheet in it with zero troubles, and that was on a Macintosh (OS X 10.3). http://www.openoffice.org/ It's free and available for a variety of platforms.
