md2notionpage

A Python package to convert Markdown text into Notion pages. This module provides functionality to create Notion pages from Markdown text, parse Markdown into Notion blocks, and process inline formatting.

Features

• Rich Markdown support - Headers, lists, code blocks, tables, images, and more
• Smart text splitting - Automatically handles Notion's 2000-character limit
• Batch processing - Efficiently handles large documents with 100+ blocks
• Cover images - Optional cover image support
• CLI & Python API - Use as a command-line tool or import as a module
• Helpful error messages - Clear guidance for common issues

Installation

pip install md2notionpage

For development:

git clone https://github.com/markomanninen/md2notion.git
cd md2notion
pip install -e .

Setup

1. Create a Notion Integration

1. Go to https://www.notion.so/my-integrations
2. Click "+ New integration"
3. Give it a name and select the workspace
4. Copy the "Internal Integration Token"

2. Get Your Parent Page ID

1. Open the page in Notion where you want to create sub-pages
2. Click "Share" → "Copy link"
3. Extract the 32-character ID from the URL
   • Example: https://notion.so/My-Page-abc123def456...
   • Page ID: abc123def456...

3. Grant Integration Access

Important: You must grant your integration access to the parent page:

1. Open the parent page in Notion
2. Click "..." (more options) → "Add connections"
3. Select your integration from the list

Without this step, you'll get "restricted_resource" errors!

4. Configure Environment Variables

Create a .env file in your project directory:

NOTION_SECRET=your_notion_integration_token_here
NOTION_PARENT_PAGE_ID=your_target_parent_page_id_here

Development

Running Tests

# Install dev dependencies
pip install -e .[dev]

# Run all tests
python -m pytest -v

# Run specific test file
python -m pytest tests/test_md2notionpage.py -v

Stress Testing

Test the splitting and batching logic with large documents:

python scripts/stress_test.py

This creates a page with:

• 3000+ character paragraph (tests text splitting)
• 150 list items (tests batch processing)
