This plugin lets you use <a href="https://github.com/erusev/parsedown" rel="nofollow ugc">Markdown</a> for individual posts on a case-by-case basis. <a href="https://github.com/thephpleague/html-to-markdown" rel="nofollow ugc">Markdown can be activated</a> using a toggle in the post editor submit box. When enabled, it replaces the WordPress post editor with <a href="https://make.wordpress.org/core/2017/10/22/code-editing-improvements-in-wordpress-4-9/" rel="nofollow ugc">CodeMirror</a> in Markdown mode.
Works on posts using the <a href="https://en-ca.wordpress.org/plugins/classic-editor/" rel="nofollow ugc">Classic Editor</a>. Gutenberg is currently not supported.

Parsedown Party

A Completely Unbiased Review

Damn simple [markdown]#via shortcode[/markdown] for wordpress. 
This plugin uses <a href="http://parsedown.org/" rel="nofollow ugc">parsedown</a> and <a href="http://highlightjs.org" rel="nofollow ugc">highlight.js</a>. Zero configuration.
Write this into the editor:
<pre><code>[markdown] 
#h1
</code></pre>
<h3>h2</h3>
<pre><code>text 
____source code (two ore more underscores will be replaced by empty spaces) 
____source code (two ore more underscores will be replaced by empty spaces) 

 `javascript
source code
 `
[/markdown]
</code></pre>
and the shortcode content will be parsed with parsedown. Syntax highlighting will appear for the source codes.
This plugin is available at <a href="https://github.com/JohannesHoppe/markdown-shortcode" rel="nofollow ugc">github</a>, too. 
Please report issues at github, pull requests are welcome, too!

Markdown Shortcode

Damn simple markdown for wordpress via shortcode, uses parsedown (parsedown.org) and highlight.js (highlightjs.org).
