md-to-docx

Markdown to Word (.docx) Skill

Convert Markdown (.md) files into professionally formatted Word (.docx) documents with embedded PNG images. Uses pure JavaScript via the docx and marked npm packages — no Pandoc, LibreOffice, or any native binary required.

How to Convert

# Install dependencies (one-time, from the scripts folder)
cd skills/md-to-docx/scripts && npm install
 
# Convert (run from workspace root)
node skills/md-to-docx/scripts/md-to-docx.mjs <input.md> [output.docx]

If output.docx is omitted, it defaults to <input-basename>.docx in the current directory.

Prerequisites

No native binaries. No system-level installs. Works on Windows, macOS, and Linux.

Features

The converter:

• Extracts YAML front-matter — uses title, date, version, audience for the title page
• Generates a title page — with project name, subtitle, date, version, and audience
• Generates a table of contents — built from H1-H3 headings
• Embeds PNG images — resolves ![alt](path) references relative to the input .md file, reads the PNG, and embeds it inline in the Word document
• Styled output — Calibri font, colored headings (#1F3864), styled tables with alternating row colors, code blocks in Consolas
• Handles all Markdown elements — headings, paragraphs, tables, code blocks, lists, images, links, horizontal rules

Image Embedding

The converter automatically embeds PNG images referenced in the Markdown:

![High-Level Architecture](diagrams/high-level-architecture.drawio.png

The image path is resolved relative to the input Markdown file. The PNG is read, dimensions are extracted from the PNG header, and the image is scaled to fit within 6 inches width while preserving aspect ratio.

If an image file is not found, a placeholder [Image not found: <path>] is inserted.

Front-Matter Format

The title is split on — or – into main title and subtitle for the title page.
