Google Docs & Spreadsheets is a free web-based word processing and spreadsheet program that keeps documents current and lets the people you choose update files from their own computers.
Import your existing documents and spreadsheets, or create new ones from scratch. All you need is a Web browser – your documents and spreadsheets are stored securely online.
There’s nothing to download; you access your documents and spreadsheets from any computer with an Internet connection and a standard browser.
Multiple people can view and make changes at the same time. There’s an on-screen chat window for spreadsheets, and document revisions show you exactly who changed what, and when.
Once you’ve created a document, you can post it to your blog. Any tags you’ve added to your document will become the post’s blog categories.
