This handles Word document creation, editing, and analysis by treating .docx files as the ZIP archives of XML they really are. You get pandoc for quick text extraction, docx-js for building new documents from scratch in TypeScript, and a Python OOXML library for surgical edits to existing files. The redlining workflow is the standout feature: it converts documents to markdown for planning, then implements tracked changes in batches directly in the XML while preserving RSIDs and only marking what actually changed. If you've ever needed to programmatically edit legal contracts or generate complex Word docs without fighting with a GUI, this gives you the low-level access to do it right.
