This tool supports loading the HTML File to transform to markdown. Click on the Upload button and select File. HTML to markdown Online works well on Windows, MAC. Node.js Parsing markdown into html, or plain text with marked.js These days I have been playing around more with a node.js project I am familiar with called marked. This is a package that can be used to parse markdown into html.

gfm | boolean | true | v0.2.1 | If true, use approved GitHub Flavored Markdown (GFM) specification. |
headerIds | boolean | true | v0.4.0 | If true, include an id attribute when emitting headings (h1, h2, h3, etc). |

sanitize | boolean | false | v0.2.1 | If true, sanitize the HTML passed into markdownString with the sanitizer function.Warning: This feature is deprecated and it should NOT be used as it cannot be considered secure. Instead use a sanitize library, like DOMPurify (recommended), sanitize-html or insane on the output HTML! |

Inline Markdown
You can parse inline markdown by running markdown through
marked.parseInline
. From scratch tembi locke.Asynchronous highlighting
Unlike
highlight.js
the pygmentize.js
library uses asynchronous highlighting. This example demonstrates that marked is agnostic when it comes to the highlighter you use.In both examples,
code
is a string
representing the section of code to pass to the highlighter. In this example, lang
is a string
informing the highlighter what programming language to use for the code
and callback
is the function
the asynchronous highlighter will call once complete.Workers
To prevent ReDoS attacks you can run marked on a worker and terminate it when parsing takes longer than usual.
Marked can be run in a worker thread on a node server, or a web worker in a browser.
