• Legacy .doc support via LibreOffice conversion

Installation

Install from PyPI (recommended)

pip install word2md

Upgrade to the latest version:

pip install --upgrade word2md

Install from source

git clone https://github.com/HNRobert/word2md.git
cd word2md
pip install -e .

Optional: legacy .doc support

Python python-docx cannot read .doc files directly. This project supports .doc by converting it to a temporary .docx using LibreOffice.

• macOS: brew install --cask libreoffice
• Ensure the soffice command is available in your PATH (LibreOffice installs it).
• Alternatively, you can set the WORD2MD_SOFFICE_PATH environment variable to the full path of your LibreOffice soffice executable (useful on Windows or custom installs).

Examples:

• macOS / Linux (bash/zsh):

# export the path to soffice binary
export WORD2MD_SOFFICE_PATH=/Applications/LibreOffice.app/Contents/MacOS/soffice

• Windows (PowerShell):

# set environment variable for current session
$env:WORD2MD_SOFFICE_PATH = 'C:\\Program Files\\LibreOffice\\program\\soffice.exe'

Usage

Command Line Tool

After installation, you can use the word2md command:

# Convert single file
word2md document.docx

# Convert legacy .doc (requires LibreOffice)
word2md document.doc

# Specify output file
word2md document.docx -o output.md

# Show verbose output
word2md document.docx -v

# Ignore all images and output a single Markdown file
word2md document.docx --ignore-images

# Batch conversion
word2md *.docx -o output_directory/

Python Script

You can also run the converter directly:

# Convert single file to auto-generated folder structure
python main.py document.docx

# Convert legacy .doc (requires LibreOffice)
python main.py document.doc

# Specify output file
python main.py document.docx -o output.md

# Show verbose output
python main.py document.docx -o output.md -v

# Ignore all images and output a single Markdown file
python main.py document.docx --ignore-images

Advanced Usage

# Batch conversion to output directory
python main.py *.docx -o output_directory/

# Output to stdout
python main.py document.docx

Project Structure

The project is now organized as a modular package:

Supported Formats

Text Formatting

• Bold → **Bold**
• Italic → *Italic*
• Underline → <u>Underline</u>

Heading Detection

The converter supports multiple methods for detecting headings:

1. Style-based detection: Converts Word heading styles (Heading 1-6, Title) to Markdown headings
2. Font-size based detection: When no heading styles are present, automatically detects headings based on font size hierarchy
   • Analyses all paragraphs with uniform font sizes
   • Determines the baseline font size (most common size, usually normal text)
   • Assigns heading levels to larger font sizes in descending order
   • Example: If baseline is 12pt, then 18pt → # (H1), 16pt → ## (H2), 14pt → ### (H3)

Headings

• Word heading styles → Markdown headings (# ## ### etc.)
• Smart title handling: When a "Title" style is present, all other headings are automatically adjusted down one level

Lists

• Unordered lists (•, -, * etc.) → - Item
• Ordered lists (1., 2., etc.) → 1. Item

Tables

• Word tables → Markdown table format

Images

• Automatic extraction of images from DOCX
• Save to assets/ directory under document name folder
• Create proper image references in Markdown: ![Image](./assets/image_001.png)
• Optional --ignore-images / --no-images mode to skip all images

Output Structure

After conversion, the following structure is created:

document_name/
├── document_name.md
└── assets/
    ├── image_001.jpg
    ├── image_002.png
    └── ...

When using --ignore-images, output is a single Markdown file (no subfolder and no assets/ directory):

document_name.md

Example

Input (DOCX)

A document with the following structure:

• Title style: "TEST DOC"
• Heading 1: "Title 1"
• Heading 2: "Title 2"
• Heading 3: "Title 3"
• Various text formatting including bold, italic, and underlined text

Output (Markdown)

# TEST DOC

## Title 1

### Title 2

#### Title 3

This is a paragraph with **bold text**, _italic text_, and <u>underlined text</u>.

- Unordered list item 1
- Unordered list item 2

1. Ordered list item 1
2. Ordered list item 2

Architecture Benefits

• Modular Design: Each component has a single responsibility
• Easy Testing: Individual modules can be tested independently
• Maintainable: Clear separation of concerns
• Extensible: Easy to add new features or modify existing ones

Key Modules

• DocxToMarkdownConverter: Main orchestrator class
• DocumentProcessor: Handles document-level processing and title detection
• ParagraphProcessor: Manages paragraph conversion and formatting
• ImageExtractor: Extracts and maps images from DOCX files
• ListProcessor: Handles ordered and unordered list conversion
• TableProcessor: Converts Word tables to Markdown format
• TextFormatter: Handles text formatting (bold, italic, underline)

Extending Functionality

The modular structure makes it easy to extend functionality:

Adding New Text Formatting

Edit docx_converter/formatting.py to add support for new text styles.

Supporting New List Types

Modify docx_converter/list_processor.py to handle different list formats.

Enhancing Image Processing

Update docx_converter/image_processor.py and docx_converter/image_extractor.py for advanced image handling.

Custom Document Elements

Add new processors in the docx_converter/ directory and integrate them via document_processor.py.

Development Workflow

1. Install dependencies: pip install -r requirements.txt
2. Run tests: python main.py assets/sample.docx
3. Add new features in appropriate modules
4. Test with various DOCX files
5. Update documentation

Manual publish to PyPI (workflow)

This repository provides a manual GitHub Action to publish the package to PyPI. The workflow is triggered via the Actions UI (Manual publish to PyPI → Run workflow).

Behaviour:

• It requires a version input (semantic version like 1.0.1).
• It will update docx_converter/__init__.py and setup.py with the provided version.
• If files change, it commits & pushes the change back to the main branch and optionally creates a v<version> tag.
• Finally it builds sdist+wheel and publishes to PyPI using the PYPI_API_TOKEN secret. If you requested a tag (the tag input), the workflow will also create a GitHub Release (tag v<version>) and upload the generated artifacts from dist/* to the release.

Set up:

• Add PYPI_API_TOKEN as a repository secret (Repository Settings → Secrets and variables → Actions → New repository secret).
• Trigger the workflow via the Actions page and supply version. To create a tag/release, check the tag checkbox.

Note: The workflow only runs on manual dispatch to avoid accidental publishes on routine pushes.

Notes

1. The converter primarily supports basic document formats; complex formatting may require manual adjustment
2. Images are automatically extracted and saved to the assets folder
3. Complex table layouts may need manual optimization
4. Some Word-specific formats have no equivalent in Markdown and will be simplified
