BIRT (Business Intelligence Reporting Tools) is an open source Eclipse-based set of reporting and data visualization tools and technologies used to build rich information applications, in particular, web applications based on Java and J2EE.
Native Excel Emitter Plugin for Birt allows you to generate reports in MS Excel 2003 and 2007 (Binary Format).
Following are the advantages:
1) Provides report in Native(Binary) MS Excel Format
2) Supports 2003 & 2007 ( So far, None of the excel emitter supports MS excel 2007 )
3) Images Support
4) Multiple Sheets Support
5) Report File Size is less, compare to other available emitters (like Default Birt XLS emitter).
Note: This is extended from the Default Birt XLS Emitter “org.eclipse.birt.report.engine.emitter.prototype.excel_2.6.2.r262_v20110215″.
