Notion.so Markdown Importer

Fork Notes:

• It is advised to create a python venv to install it with * python3 -m venv venv-name
• To use it install requirements first with pip3 with * pip3 install -r requirements.txt
• Then install it with * pip3 install ./: warnings are displayed but the installation works

An importer for Markdown files to Notion.so using notion-py

It provides these features over Notion.so's Markdown importer:

• Picking a Notion.so page to upload to (instead of them all uploading to the root)
• Code fences keep their original language (or as close as we can match it)
• Code fences are formatted properly
• Inline HTML is preserved
• (Optionally) Upload images that are memtioned in the HTML <img> tags.
• Markdown frontmatter is preserved
• Local image references will be uploaded from relative URLs
• Image alts are loaded as captions instead of as TextBlocks
• Handles nested lists properly
• Among other improvements...

Supports Python 3.6+

Usage from CLI

• pip install md2notion
• Then run like python -m md2notion [token_v2] [page-url] [...markdown_path_glob_or_url]
• The markdown at the given path will be added as a new child to the Notion.so note at page-url

There are also some configuration options:

• --clear-previous: If a child of the note at page-url has the same name as what you're uploading, it will first be removed.
• --append: Instead of making a new child, it will append the markdown contents to the note at page-url
• --html-img: Upload images that are memtioned in the HTML <img> tags.

Usage from script

• pip install md2notion
• In your Python file:

from notion.client import NotionClient
from notion.block import PageBlock
from md2notion.upload import upload

# Follow the instructions at https://github.com/jamalex/notion-py#quickstart to setup Notion.py
client = NotionClient(token_v2="<token_v2>")
page = client.get_block("https://www.notion.so/myorg/Test-c0d20a71c0944985ae96e661ccc99821")

with open("TestMarkdown.md", "r", encoding="utf-8") as mdFile:
    newPage = page.children.add_new(PageBlock, title="TestMarkdown Upload")
    upload(mdFile, newPage) #Appends the converted contents of TestMarkdown.md to newPage

If you need to process notion-py block descriptors after parsing from Markdown but before uploading, consider using convert and uploadBlock separately. Take a look at upload.py#upload() for more.

from md2notion.upload import convert, uploadBlock

rendered = convert(mdFile)

# Process the rendered array of `notion-py` block descriptors here
# (just dicts with some properties to pass to `notion-py`)

# Upload all the blocks
for blockDescriptor in rendered:
    uploadBlock(blockDescriptor, page, mdFile.name)

If you need to parse Markdown differently from the default, consider subclassing NotionPyRenderer (a BaseRenderer for mistletoe). You can then pass it to upload(..., notionPyRendererCls=NotionPyRenderer) as a parameter.

Example, Custom Hexo Importer

Here's an example that imports a Hexo blog (slghtly hacky).

import io
import os.path
import glob
from pathlib import Path
from notion.block import PageBlock
from notion.client import NotionClient
from md2notion.upload import upload

client = NotionClient(token_v2="<token_v2>")
page = client.get_block("https://www.notion.so/myorg/Test-c0d20a71c0944985ae96e661ccc99821")

for fp in glob.glob("../source/_posts/*.md", recursive=True):
    with open(fp, "r", encoding="utf-8") as mdFile:
        #Preprocess the Markdown frontmatter into yaml code fences
        mdStr = mdFile.read()
        mdChunks = mdStr.split("---")
        mdStr = \
f"""```yaml
{mdChunks[1]}
`` `

{'---'.join(mdChunks[2:])}
"""
        mdFile = io.StringIO(mdStr)
        mdFile.__dict__["name"] = fp #Set this so we can resolve images later

        pageName = os.path.basename(fp)[:40]
        newPage = page.children.add_new(PageBlock, title=pageName)
        print(f"Uploading {fp} to Notion.so at page {pageName}")
        #Get the image relative to the markdown file in the flavor that Hexo
        #stores its images (in a folder with the same name as the md file)
        def convertImagePath(imagePath, mdFilePath):
            return Path(mdFilePath).parent / Path(mdFilePath).stem / Path(imagePath)
        upload(mdFile, newPage, imagePathFunc=convertImagePath)
