Docs & OfficeIntermediate★ 33,030⑂ 3,248AI score 10/10Last updated: Aug 9, 2026

What it does

  • Generates polished Word documents with the docx npm library (TOC, headings, tables, images, page numbers).
  • Edits existing files by unzipping, patching word/document.xml, and re-zipping with XSD validation.
  • Handles tracked changes (<w:ins>/<w:del>) and multi-file comment plumbing via helper scripts.
  • Verifies output by converting to PDF and rendering page images for visual review.

Who it's for

  • Anyone who must deliver professional Word files: reports, memos, letters, contracts.
  • Legal/contract reviewers who need accurate redlines and comments.
  • Developers building document generation pipelines.

Examples

  1. "Turn this markdown draft into a Word report with a table of contents and page numbers."
  2. "Redline clause 3 of the contract under my name and attach a comment explaining why."
  3. "Swap the logo image in this .docx and render the pages to confirm the tables still look right."
