Google has inched further in to the realm of the web-based office with the launch of Google Spreadsheets.
Create basic spreadsheets from scratch.
You can start from scratch and do all the basics, including changing the number format, sorting by columns, and adding formulas.
Upload your spreadsheet files.
Upload spreadsheets or worksheets from CSV or XLS format – all your formulas and formatting will come across intact.
Familiar desktop feel makes editing a breeze.
Just click the toolbar buttons to bold, underline, change the font, change the cell background color and more.
It is an invite-only service right now. I am guessing that Google learned from the past when they launched services like Pages and Analytics openly, only to have to lock them down after getting saturated with account requests.
