MD-DOCX Converter

A Python tool for bidirectional conversion between Markdown (.md) and Microsoft Word (.docx). Designed to make it easy to move content between Word documents and AI tools like Claude, ChatGPT, and GitHub Copilot.

What it does

• Converts .md → .docx with correct heading hierarchy (Title, Heading 1–9)

• Converts .docx → .md as clean GitHub Flavored Markdown (GFM)

• Runs from a simple desktop shortcut — no command line knowledge needed

• Handles headings, bold/italic/strikethrough, lists, task lists, tables, blockquotes, code blocks, images, and hyperlinks

See MarkdownSyntax.md for the full element mapping and notes on what is preserved, approximated, or dropped.

Requirements

• Windows 10/11

• Python 3.11+

• The following Python packages (installed via pip):

pip install markdown-it-py python-docx

Setup

1. Clone the repository

git clone https://github.com/cjwpenner/md-docx-converter.git
cd md-docx-converter

2. Install dependencies

pip install markdown-it-py python-docx

3. Create the desktop shortcut

pip install pywin32
python create_shortcut.py

This creates an MD-DOCX Converter shortcut on your Windows desktop. pywin32 is only needed to create the shortcut — it is not required to run the converter itself.

4. Run the converter

Double-click MD-DOCX Converter on your desktop. A console window opens and prompts:

MD ↔ DOCX Converter
--------------------
Enter file path:

Paste or type the full path to your .md or .docx file and press Enter. The converted file is saved in the same directory with the extension swapped.

You can also run directly from the command line:

python md_docx_converter/converter.py

Conversion notes

Heading hierarchy

The heading level mapping is context-dependent:

• MD → DOCX: If there is exactly one # in the document, it becomes a Word Title. All other headings shift down by one level. If there are multiple # headings, they all become Heading 1 with no Title.

• DOCX → MD: If the document has a Title style, it becomes #. All headings shift up accordingly. If there is no Title, Heading 1 becomes #.

Lossy elements

Word formatting that has no Markdown equivalent is approximated as bold:

Images

• DOCX → MD: Embedded images are extracted to a {filename}_images/ folder next to the output .md file.

• MD → DOCX: Images referenced by relative path are re-embedded. Missing images become [image not found: path].

MCP server (Claude / AI integration)

This tool is also available as an MCP server, letting Claude and other AI assistants read and write Word documents directly.

Install

pip install mcp-md-docx

Configure Claude Desktop

Add to %APPDATA%\Claude\claude_desktop_config.json:

{
  "mcpServers": {
    "md-docx": {
      "command": "python",
      "args": ["-m", "mcp_md_docx"]
    }
  }
}

Configure Claude Code

claude mcp add md-docx mcp-md-docx

Tools exposed

Once configured, you can say things like:

• "Read report.docx and summarise it"

• "Turn this into a Word document and save it to my Desktop"

• "Convert all the bullet points in notes.docx into a table"
