Tips

  • Strings that look like reserved words (true, false, null) are automatically quoted.
  • Numbers, booleans, and null are emitted as bare YAML scalars.
  • Nested objects and arrays use YAML block style (indented, human-readable).
  • Multi-line strings are emitted as quoted scalars with escape sequences.

FAQ
What types of JSON values does this converter handle?+

All standard JSON types: objects (converted to YAML block mappings), arrays (block sequences), strings (quoted when necessary), numbers, booleans (true/false), and null. Nested structures of any depth are supported.

Why are some strings quoted in the YAML output?+

YAML has reserved words like true, false, null, yes, no, on, and off. Strings that look like numbers or reserved words would be misread by a YAML parser if left bare, so the converter wraps them in double quotes automatically.

Is my JSON data sent to a server?+

No. The entire conversion happens in your browser using JavaScript. Nothing is uploaded or stored — your data stays completely private.

Can I download the YAML output?+

Yes. After conversion, click the Download .yaml button to save the result as a .yaml file to your computer.
