## What it is
docx4j is an open-source (Apache v2) Java library for creating, editing, and saving Microsoft OpenXML packages, including Word docx, PowerPoint pptx, and Excel xlsx files, using JAXB for the in-memory object representation. It offers power at the file-format level: document generation via data binding or MERGEFIELD, CustomXML binding, transforms, and export to HTML or PDF.

## Use cases
- generate word documents from templates in java
- read and edit docx files programmatically
- convert docx to pdf in java
- mail merge into docx templates with MERGEFIELD or content controls
- create or modify powerpoint pptx presentations from java
- manipulate excel xlsx workbooks from java
- export word documents to html

## When to choose
- You need format-level control over OpenXML documents from Java - anything the file format supports can be done
- You need document generation via variable binding, content controls, or MERGEFIELD with repeats and conditionals
- You need docx-to-PDF or docx-to-HTML export without driving a full Office installation
- You are on Java 11+ and want an actively maintained OpenXML library with JPMS modularised releases

## When to avoid
- You are not on the JVM - this is a Java library, similar to Microsoft's OpenXML SDK but for Java
- You want a simple high-level API and are unwilling to learn JAXB and the Open XML file structure
- You are stuck on legacy Java 8 - docx4j-8 is unsupported
- You need only trivial text extraction where a lighter-weight parser would suffice
