Guide

YAML to JSON: what it does and how to use it

What this YAML tool does

This converter turns YAML documents into formatted JSON. It is useful when moving configuration between systems, checking YAML syntax, or converting readable config files into machine-friendly JSON for APIs, build tools, and automation scripts.

How it works

Paste YAML into the editor and the browser parses it with a YAML parser. If the document is valid, the parsed value is printed as indented JSON. If the YAML has indentation, quoting, or structure errors, the tool shows the parser message so you can fix the input.

Examples

  • Convert CI configuration snippets to JSON.
  • Turn Kubernetes-style YAML examples into JSON for documentation.
  • Validate indentation before committing a config file.

Security considerations

Conversion runs client-side. Config files can contain tokens or URLs, so keep sensitive YAML on trusted machines and avoid sharing output that includes secrets.

FAQ

Does YAML support comments?

Yes, but comments are not preserved in JSON because JSON has no comment syntax.

Can this convert multiple documents?

Use one YAML document at a time for predictable output.

Is the YAML sent to the server?

No. Parsing and JSON formatting happen in your browser.
