Hey look, there's a tutorial on how to do this link from the JExecel website!

Side note: It looks like JExcel is file based only. This means you can't interact with an open spreadsheet. If you need to interact with an open spreadsheet you will have to use JNI or a library such as J-Integra COM , which uses JNI.
