Another week, another Google product launches. Or almost launches in this case. Google hasn’t opened up Google Spreadsheets, an Ajax spreadsheet, to the general public yet but they have published a tour of what the product will look like once it actually does launch, and you can request an invitation to try it out.
Files can be imported in CSV or XLS formats, so excel documents and other spreadsheet files should work in Google Spreadsheets. Files can be saved in CSV, XLS and HTML formats.
