Open Source Java API for Word DOCX Documents

Create, Read, Edit and Convert Microsoft Word DOCX files, add text & tables via Java library.

DOCX4J is JAXB-based open source(Apache v2) library for manipulating Microsoft Office file formats. It provides the functionality to read, write, edit & and save Microsoft Word 2007 DOCX file format.

DOCX4J is similar to Microsoft's OpenXML SDK, but for Java. It uses JAXB to create the in-memory object representation. Using the API you can generate Mircosoft Office documents, edit them, format the text & paragraphs, insert tables & images and manage other form elements, and much more. Basically, its emphasis is on power, if the format supports it you can do it using the API.
