JSON vs YAML vs XML

JSON is lightweight and strict, YAML is human-friendly and indentation-based, and XML is tag-driven with attributes. Use JSON for APIs, YAML for configs, and XML when you need attributes or schemas.

How to get clean output

Run Convert for a validated transform, then Prettify for readability or Minify for compact payloads. Swap flips formats so you can round-trip without retyping.

Everything runs in your browser. No files leave your machine, so sensitive configs and payloads stay private.
