# Plutext

> Plutext Pty Ltd created and sponsors docx4j, the open-source (Apache License 2.0) Java library for Office OpenXML (docx/pptx/xlsx), and sells Docx4j Enterprise, whose key parts are MergeDocx (merge/concatenate Word documents without loss of formatting) and MergePptx (the same for PowerPoint presentations), plus OLE embedding and digital signature helpers. Docx4j Enterprise is available with source code, and its licences are verified locally with no online activation.
