How to convert a Google Doc to Markdown
To convert a Google Doc to Markdown, paste a public Google Docs document URL into the tool. The converter extracts the document id, requests Google's HTML export, turns the exported HTML into Markdown, and opens the output in the Markdown workspace. From there you can edit, copy, download .md, or export the preview. If the document is private or restricted, the export will fail because this MVP does not use OAuth.
