About JWorkbook

JWorkbook is a class library for creating spreadsheet files from Java. This version can save files in Gnumeric format. In addition, there is partial support for the Excel file format, thanks to the POI project. JWorkbook is licensed under the terms of the GNU Lesser General Public Licence (LGPL).

As part of this project, we've compiled information about the Gnumeric file format.


The Javadoc HTML pages for JWorkbook are available online and can be generated locally from the source code.


The JWorkbook discussion forum is the place to ask questions, request new features, report bugs and make any comments about the JWorkbook class library.



JWorkbook requires the Java 2 platform (JDK version 1.2.2 or later).
