Doc to Markdown

Converts DOCX, PDF and PPTX files into clean Markdown with eight automatic post-processing fixes.

Docs & OfficeIntermediate★ 1,323⑂ 212AI score 10/10Last updated: Aug 8, 2026

What it does

  • Converts DOCX / PDF / PPTX / XLSX to Markdown, picking the best tool per format (pandoc, pymupdf4llm, markitdown).
  • Applies eight automatic DOCX cleanups: broken grid/simple tables, nested media/media/ image paths, leftover {width=...} attributes, escaped brackets, double-bracket links, and indented code blocks.
  • Fixes CJK bold rendering by inserting whitespace around ** spans that contain CJK characters.
  • Offers Quick mode (fast) and Heavy mode (runs tools in parallel, scores segments, merges the best table/image/heading versions).
  • Ships validation tooling that measures text/table/image retention and can emit an HTML report, plus a PDF image extractor with metadata.

Who it's for

  • Technical writers moving Word/PDF material into wikis or Git repos.
  • Anyone handling Chinese/Japanese/Korean documents plagued by bold and table glitches.
  • Engineers preparing document corpora for RAG or LLM pipelines.

Example uses

  1. "Convert spec.docx to markdown" → clean .md with images extracted to ./media.
  2. "Pull every figure out of this PDF" → extract_pdf_images.py outputs images plus a metadata JSON.
  3. "Did the conversion lose anything?" → validate_output.py produces a pass/warn/fail retention report.
