The Apache POI consists of APIs for manipulating various file formats based upon Microsoft's OLE 2 Compound Document format, and Office OpenXML format, using pure Java. In short, you can read and write MS Excel files using Java.

In addition, you can read and write MS Word and MS PowerPoint files using Java. POI is your Java Excel solution (for Excel 97-2007). However, we have a complete API for porting other OLE 2 Compound Document formats and welcome others to participate.

OLE 2 Compound Document Format based files include most Microsoft Office files such as XLS and DOC as well as MFC serialization API based file formats.

Office OpenXML Format based files include the new (2007+) xml based file formats, including Microsoft office files such as XLSX, DOCX and PPTX.
