an embeddable spreadsheet for your web application
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. The user interface is written entirely in JavaScript and its server-side API is pure Java based on the OpenXLS spreadsheet engine. Neither the client nor the server needs Excel or any browser plugins.
Sheetster is primarily intended...
This program converts, compares, merges, normalizes, and refactors data to and from disparate sources (CSV, Excel, and any JDBC/ODBC database) for use in a Java program.
