Sheetster is a web-based spreadsheet editor and viewer. It can import and export the XLS and XLSX file formats and nearly the full range of Excel formula functions are supported. Most basic features are implemented as well as some of the more advanced ones.

Neither the client nor the server needs Excel or any browser plugins. Sheetster is primarily intended for developers who want to integrate spreadsheets into their web applications.
