Convert HTML to Markdown

By  on  

One of my biggest mistakes with this blog was not finding a WordPress plugin that would allow me to write my posts with markdown; to this day I still need to write posts in "Visual" mode and then manually convert the post to HTML for "Text" mode.  One of these days I want to convert existing posts to Markdown and then enable a plugin that will convert Markdown to HTML. This painful process made me ask myself:  is there a way I can use Node.js JavaScript to convert HTML to Markdown?  There is, and it's called Turndown by Dom Christie.

Convert HTML to Markdown with Node.js

Start by installing Turndown:

yarn add turndown

Then use Turndown's simple API to convert HTML to markdown:

var TurndownService = require('turndown');
var turndownService = new TurndownService();

var markdown = turndownService.turndown(`

You can use the interactive Turndown demo to experiment with its capabilities.  Turndown has a number of options and allows you to use filters to keep elements you believe could be at risk for improper conversion.

Most developers look for a Markdown to HTML solution so it's rate to find myself in a position to need to convert HTML to Markdown.  I look forward to migrating my site's content to Markdown so that writing posts is much less stressful in the future!

    MooTools HTML Police: dwMarkupMarine

    We've all inherited rubbish websites from webmasters that couldn't master valid HTML. You know the horrid markup: paragraph tags with align attributes and body tags with background attributes. It's almost a sin what they do. That's where dwMarkupMarine comes in.

  1. Hi David,

    there’s even more you can do with it!

    We explored it in a hackathon:
    Exporting content from Confluence using its ReST api and feed the markdown to a static site generator (like Netlify or Hapi.js).

    Was quite fun :-)

    Sadly I can’t share details because of work during business hours :-(

    Cheers
