Docs to Markdown (GD2md-html) converts Google Docs™ to simple, readable Markdown or HTML. 

This add-on allows you to create documents using the excellent editing and collaborative features of Google Docs, then convert to Markdown or HTML to use on your web site.

Note that Docs to Markdown marks up the content (headings, paragraphs, lists, code blocks, etc.) but does not preserve colors and styles in text or tables.

See https://github.com/evbacher/gd2md-html/wiki for docs. See  https://github.com/evbacher/gd2md-html/ for the source.
