Does it handle nested JSON?

Yes. Nested objects and arrays are converted to YAML block style with correct indentation at every depth level.

Is the output valid YAML?

Yes. The output is YAML 1.2 compliant. Special characters in string values are properly quoted to ensure validity.

Does it support YAML flow style vs block style?

By default the output uses block style (one key per line) which is more readable. Toggle to flow style for compact inline output, equivalent to the original JSON structure.

Will null, boolean, and number types be preserved?

Yes. JSON null converts to YAML null, true/false remain booleans, and numbers stay as numbers without quotes — YAML is type-aware, so the types are faithfully preserved.

JSON to YAML Converter

Converts JSON objects and arrays into YAML format using proper indentation and YAML syntax conventions. Supports all JSON data types: strings, numbers, booleans, null, arrays, and nested objects. The output is valid YAML 1.2 compatible with Kubernetes, Docker Compose, Ansible, and most CI/CD tools.

Runs entirely in your browser — your input is never uploaded, stored, or logged.

Paste your JSON and get clean, readable YAML output ready to use in any configuration file. To go the other way, use the YAML to JSON converter.
