Google has just launched a spreadsheet (Excel) software on the net. This allows you not only to edit and save your spreadsheets on the internet (which means they are stored on secure servers and you’ll never lose your data due to a hard disk crash), but also allows you to get multiple people working on the spreadsheet.
Whats more.. its completely free and dosent take a lot of hard disk space like Microsoft softare!! And its never going to crash.
Have a look at spreadsheets.google.com
