Convert YAML to JSON online — paste YAML and get clean, validated JSON. Handles nested mappings, sequences, inline flow collections, comments, and typed scalars (numbers, booleans, null). Runs in your browser; nothing is uploaded.
Paste your YAML above and it converts to pretty-printed JSON instantly. Mappings become objects, sequences become arrays, and scalars are typed as numbers, booleans, null, or strings.
Block mappings and sequences, nested structures, inline flow collections ({a: 1} and [1, 2]), quoted and bare scalars, and comments. Anchors, aliases, and block scalars (| and >) are not supported and are reported with a clear message.
No — the conversion runs entirely in your browser, so your data never leaves your machine.
