About this tool

YAML structure is preserved as objects and arrays, making it easy to inspect hierarchy, fix indentation issues, and feed JSON-only toolchains.

How to use

  1. Paste YAML text.
  2. View formatted JSON output or parse errors.
  3. Copy the result for APIs, scripts, or config validation.

FAQ

Are arrays and nested objects preserved?

Yes. YAML lists, objects, booleans, and numbers map to the corresponding JSON types—not plain strings.

Can indentation errors be located?

Parse failures show underlying parser messages that usually point to indentation or colon issues.

Does it support multi-document YAML?

Single-document YAML is the primary use case. Split multi-document inputs before converting.

Is my YAML uploaded?

No. Conversion runs locally in your browser.
