This is an incomplete Google Apps Script that I use to convert a Google Doc to a markdown document. It supports basically the features I needed to write one blog post
Features:
- Paragraphs, Heading 1-6
- Simple lists (list is contiguous, and single-paragraph per list item)
- Links, strong, emphasis. If they start or end with a space, the span is shortened (because Markdown does not support strong and emphasis on a space boundary). But strong/emphasis within a word will result in incorrect markdown, so don’t do emphasis within a word.
- Blockquote
- Footnotes (they all go on the very bottom rather than the bottom of each section)
Not supported
- No escaping of markdown characters within the text yet (
*,**,#, etc.) - No prevention of complicated formatting (emphasis within words, bold and emphasis starting at the same time, etc.)
- Images
- Tables
Prerequisite: install node.js
npm i # installs clasp
# Open a Doc, open Script editor, copy File → Project Properties → Script ID
npx clasp clone <scriptId> # sets scriptId in .clasp.json. Warning: overwrites files!
npx clasp push
# In Script Editor, run onStart (which registers the menu item)
# Then, in the document, run the command Add-ons → toMd → Start from the top menu
Prerequisite: install node.js
npm i # installs typescript
cd test
npx mocha -r ts-node/register markdotntostringtest.ts
