HTML to Markdown NodeRED Node

A Node-RED node that converts HTML content into Markdown format.

Features

• Converts HTML tags like <h1> to #, <p> to paragraph text, <ul>/<ol> to lists, and <a> to Markdown links.
• Useful for transforming rich text content into Markdown for storage, APIs, or display in Markdown renderers.

Install

From your Node-RED user directory (~/.node-red):

npm install node-red-contrib-to-markdown

Usage

Add the to-markdown node to your flow. Pass HTML content to the payload property, and the node will output the corresponding Markdown.

Example Input

{
  "payload": "<h1>Title</h1><p>This is a paragraph.</p><ul><li>Item 1</li><li>Item 2</li></ul><a href='https://example.com'>Link</a>"
}

Example Output

This is a paragraph.

- Item 1
- Item 2

[Link](https://example.com)
