WHAT IS YAML TO JSON?

Convert YAML to pretty-printed JSON. It is parsed safely, never executing custom tags or code.

How to use?

  1. Paste or upload your YAML.
  2. Click Convert and review the JSON output.
  3. Copy or download it.

Frequently asked questions

Will a custom YAML tag get executed?

No — parsing uses a safe schema with no code-executing tag support. An unrecognized tag is reported as a parse error, never silently ignored or executed.

Are multi-line block scalars handled correctly?

Yes — YAML's block scalar syntax (| and >) parses into a single multi-line string, correctly represented with \n line breaks in the JSON output.

Will malformed YAML crash the tool?

No — a parse failure shows a clear error message and keeps your original input untouched; it never clears your input or crashes the page.

Conversion runs entirely in your browser — nothing you paste or upload here is sent to any server.
