The benefits of an online spreadsheet is not that its going to be better and more feature rich than excel, but the fact that several people can be involved in editing it, without the need to 20 copies of it to end up clogging up your email. It’s also got integrated chat, so you can collaborate on it “live”.

Besides, its a cute name Numbler.com and is as simple to set up and get going on as the wonderful collaborative writing tools from 37signals called writeboard.

I setup a demo spreadsheet here if you want to try it out: http://numbler.com/LIwJf5VYcIpPZQA8

So what’s missing?

• Cut and paste, no spreadsheet can survive without that
• Dragging cells
• Highlighting cells to insert them into a formula
• Runs a little slow on firefox on the mac
