DOCX Creation, Editing & Redlining

An end-to-end skill for creating, editing, analyzing, and redlining Word (.docx) documents with real tracked changes.

Docs & OfficeIntermediate★ 164⑂ 11AI score 10/10Last updated: Sep 13, 2026

What it does

  • Read & analyze: converts .docx to markdown via pandoc, preserving tracked changes.
  • Create new documents: builds Word files programmatically with the docx npm library (docx-js).
  • Edit existing documents: unpacks the .docx, edits word/document.xml through a Python Document library, then repacks it.
  • Professional redlining: inserts genuine tracked changes using <w:ins>/<w:del>, batched 3–10 edits at a time, with minimal-diff precision and final verification.
  • Visual review: converts DOCX → PDF → JPEG pages with LibreOffice and poppler to inspect layout.

Who it's for

  • Legal, business, and academic reviewers who must leave an auditable edit trail
  • Developers automating Word report or contract generation
  • Anyone needing precise Word edits without breaking original formatting

Examples

  1. "Change every '30 days' to '60 days' in this contract as tracked changes" → only the changed token is marked, surrounding runs preserved
  2. "Extract this NDA to markdown and summarize risky clauses"
  3. "Generate a monthly report .docx with headings and a table" → docx-js script outputs the file
