JSON to YAML

Convert JSON to clean, indented YAML — objects become mappings and arrays become sequences. Runs in your browser.

Frequently asked questions

Is YAML just formatted JSON?

YAML is a superset of JSON — every JSON document is valid YAML. This converts the JSON structure into idiomatic block-style YAML.

Does it handle nested data?

Yes, nested objects and arrays are indented as YAML mappings and sequences.
