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:

Word formatting	Markdown output
Underline	**bold**
Highlight	**bold**
Small caps	**bold**
Font colour	Stripped (text kept)

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].

Claude Code integration

This tool integrates with Claude Code as either a plugin (recommended — gets everything in two commands) or a standalone MCP server (for manual setup or Claude Desktop).

Option A: Claude Code plugin (recommended)

The plugin bundles the MCP server configuration and a /convert skill. Run these two commands inside Claude Code:

/plugin marketplace add cjwpenner/md-docx-converter
/plugin install md-docx-converter@md-docx-converter

That is it — no further configuration needed. After running /reload-plugins, Claude gains the conversion tools and you can invoke the skill directly:

/md-docx-converter:convert path/to/file.md
/md-docx-converter:convert path/to/report.docx

Or just ask naturally: "Convert this to a Word document" and Claude will use the tools automatically.

Option B: MCP server only (manual setup)

Use this if you want just the MCP tools without the plugin, or if you are configuring Claude Desktop rather than Claude Code.

Install the package:

pip install mcp-md-docx

Claude Code — register the MCP server:

claude mcp add md-docx-converter --transport stdio -- uvx mcp-md-docx

Claude Desktop — add to %APPDATA%\Claude\claude_desktop_config.json:

{
  "mcpServers": {
    "md-docx-converter": {
      "type": "stdio",
      "command": "uvx",
      "args": ["mcp-md-docx"]
    }
  }
}

Tools exposed

Tool	What it does
read_docx	Read a .docx file — returns full Markdown text to the AI
write_docx	Create a .docx from Markdown text the AI has written
convert_md_file_to_docx	Convert a .md file on disk to .docx
