Word to Markdown Conversion

Ingest Word documents into your Markdown workflow — clean, linted, version-control ready

Staleness Watch: See EXTERNAL-API-REGISTRY.md for source URLs and recheck cadence

Convert .docx files into clean, linted Markdown with extracted images, normalized headings, and cleaned table formatting. The reverse converter for ingesting external documents into a Markdown-based workflow.

---

When to Use

• Importing Word documents from stakeholders into a Markdown-based workflow
• Converting legacy documentation to Markdown for version control
• Extracting content from .docx for further processing (presentations, email, web)
• Onboarding external resources (SOWs, RFPs, specs) into project repositories
• Migrating from Word-based documentation to docs-as-code
• Preparing content for static site generators (VitePress, Docusaurus, etc.)

---

Supported Content

Content Type	Status	Notes
Headings	✅	Hierarchy normalized to start at H1
Bold/Italic	✅	Converted to Markdown syntax
Links	✅	Preserved as Markdown links
Images	✅	Extracted to images/ folder
Tables	✅	Cleaned and aligned
Lists	✅	Ordered, unordered, nested
Code blocks	⚠️	Detected if styled as code
Footnotes	✅	Converted to Markdown footnotes
Comments	⚠️	Stripped with --strip-comments
Track changes	❌	Accept/reject before converting
Embedded objects	❌	Extract manually

---

Key Features

Feature	Details
Image extraction	Embedded images saved to images/ folder with sequential naming
Pandoc cleanup	Removes escaped brackets, span classes, trailing backslashes
Table normalization	Aligns columns, adds proper separators
Heading fix	Normalizes hierarchy to start at H1
Frontmatter	Optional YAML frontmatter with title and date
Comment stripping	Removes Word review comments

---

Usage

# Basic conversion
node .github/muscles/docx-to-md.cjs report.docx

# With frontmatter and heading normalization
node .github/muscles/docx-to-md.cjs spec.docx --add-frontmatter --fix-headings

# Strip review comments
node .github/muscles/docx-to-md.cjs reviewed.docx --strip-comments

# Custom output path
node .github/muscles/docx-to-md.cjs input.docx output/document.md

# Debug mode (keeps raw pandoc output)
node .github/muscles/docx-to-md.cjs input.docx --debug

# Full cleanup pipeline
node .github/muscles/docx-to-md.cjs spec.docx --add-frontmatter --fix-headings --strip-comments --clean-tables

---

Options Reference

Option	Default	Description
--extract-images	true	Extract images to images/ folder
--no-extract-images	-	Keep images as raw base64 in markdown
--add-frontmatter	off	Generate YAML frontmatter with title/date
--clean-tables	true	Normalize table column widths
--no-clean-tables	-	Keep pandoc raw table output
--fix-headings	off	Normalize heading hierarchy to start at H1
--wrap N	0	Wrap lines at N characters (0 = no wrap)
--strip-comments	off	Remove Word comment annotations
--debug	off	Keep intermediate pandoc output

---

Post-Processing Pipeline

The conversion follows a multi-stage cleanup:

.docx → pandoc → raw MD → cleanup → clean MD
                            ↓
                    1. Escaped brackets removed
                    2. Trailing backslashes removed
                    3. Span classes stripped
                    4. Image attributes cleaned
                    5. Comments stripped (optional)
                    6. Headings normalized (optional)
                    7. Tables reformatted
                    8. Images extracted
                    9. Frontmatter added (optional)

Pandoc Cleanup Details

Pandoc Quirk	Before	After
Escaped brackets	\[text\]	[text]
Trailing backslashes	line\	line
Span classes	{.underline}	(removed)
Image attributes	{width="5in"}	(removed)
Heading anchors	{#section-1}	(removed)
Excessive blank lines	\n\n\n\n	\n\n

---

Image Extraction

Embedded images are extracted to a sibling images/ folder:

input/
├── document.docx
└── document.md (output)
    └── images/
        ├── image1.png
        ├── image2.png
        └── image3.jpg

Image references in markdown are updated automatically:

![](images/image1.png)

Common Workflows

Stakeholder Document Ingestion

# Convert with full cleanup
node .github/muscles/docx-to-md.cjs stakeholder-spec.docx \
  --add-frontmatter --fix-headings --strip-comments

# Validate output
node .github/muscles/markdown-lint.cjs stakeholder-spec.md

# Review and commit
git add stakeholder-spec.md images/
git commit -m "docs: ingest stakeholder specification"

Legacy Documentation Migration

# Batch convert all Word docs
Get-ChildItem *.docx | ForEach-Object {
  node .github/muscles/docx-to-md.cjs $_.FullName --add-frontmatter --fix-headings
}

---

Troubleshooting

Problem	Cause	Solution
"pandoc not found"	pandoc not installed	winget install pandoc
Images missing	Extraction failed	Check images/ folder, re-run
Tables misaligned	Complex table structure	Manual cleanup may be needed
Headings start at H3	Original doc structure	Use --fix-headings
Comments in output	Track changes not stripped	Use --strip-comments
Encoding issues	Non-UTF8 content	Re-save .docx as UTF-8

---

Limitations

• Track changes: Accept or reject all changes in Word before converting
• Embedded objects: Charts, SmartArt, etc. must be extracted manually
• Complex tables: Merged cells may not convert cleanly
• Styles: Word styles are lost (only structural elements preserved)
• Headers/footers: Not extracted (document body only)

---

Requirements

• Node.js 24+
• pandoc (winget install pandoc)

Conversion Acceptance Decision Table

Condition	Verdict	Action
All headings mapped to correct # levels	Accept	Verify no skipped heading levels
Headings rendered as bold paragraphs instead of #	Reject	Check pandoc --shift-heading-level and source styles
Tables converted to valid Markdown pipe tables	Accept	Spot-check alignment
Complex tables (merged cells) lose structure	Warning	Manual restructure or use HTML table fallback
Images extracted and linked with relative paths	Accept	Verify image files exist in output dir
Images lost or referenced with absolute Windows paths	Reject	Use --extract-media with correct output dir
Footnotes converted to Markdown footnote syntax	Accept	Verify numbering is sequential
Footnotes lost or inlined as parenthetical text	Warning	Check pandoc footnote handling
Code blocks preserve monospace and indentation	Accept	Verify language fence tags present
Track changes / comments stripped from output	Accept	Expected — Markdown has no change tracking
Track changes rendered as visible markup	Reject	Accept or reject all changes before conversion
Bullet and numbered lists preserve nesting	Accept	Verify indent levels match source
Output passes markdownlint with zero errors	Accept	Run lint-clean-markdown post-conversion
Round-trip (docx→md→docx) preserves semantic content	Accept	Formatting differences OK; content loss is not
