Google Spreadsheets is a Web-based application that allows users to create, update and modify spreadsheets and share the data live online. The Ajax-based program is compatible with Microsoft Excel and CSV (comma-separated values) files. Spreadsheets can also be saved as HTML.
Google's product offers typical spreadsheet features, such as the ability to add, delete and sort rows and columns. The application also enables multiple, geographically dispersed users to collaborate on a spreadsheet in real time and chat through a built-in instant messaging program. Users can upload spreadsheets directly from their computers.
A beta version of Google Spreadsheets was offered to Google subscribers in June 2006. Early reports indicated that, at least in beta, Google's offering was lightweight, lacking the full functionality of a product like Excel. Other Ajax-based spreadsheet applications include ZohoSheet, iRows and numsum.
In August 2006, Google launched a suite of Web-based, ad-supported office applications called Google Apps for Your Domain.
