Anatomy of a DOCX XML Structure

Office Open XML (OOXML)

Introduced in Office 2007, the .docx format replaced the proprietary binary .doc format. It is a ZIP file containing XML documents.

The core content lives in word/document.xml. Paragraphs are defined by <w:p> tags, text runs by <w:r>, and actual text by <w:t>. Formatting is applied via separate style references.

Use our DOCX Analyzer to view the raw XML structure.

FAQ

Can I write a DOCX file using Python?

Yes, using libraries like python-docx, which abstract the XML generation. Or you can generate the XML manually and zip it.
