Learn how the tool works and when to use it.

The Markdown Metadata Generator converts a JSON object into standard YAML front matter that can be pasted at the top of a Markdown file. The generated block uses the --- delimiters expected by static site generators.

Why Use This Tool?

Front matter is the metadata block at the top of Markdown files used by Jekyll, Hugo, Eleventy, and similar tools. Writing it by hand means keeping dashes, indentation, and value types consistent. This tool produces that block from a JSON object so the result is ready to paste.

How It Works

  • Paste a JSON object into the input editor.
  • Click Generate to send it to the conversion API.
  • View the YAML front matter in the output panel.
  • Copy the front matter or download it as a .md file.

Key Features

  • JSON object to YAML front matter conversion
  • Standard --- delimited front matter block
  • Live input key count and JSON status
  • Copy and download generated YAML
