What JSON can I convert?

Any valid JSON — nested objects, arrays, strings, numbers, booleans and null. The output uses two-space indentation and quotes any string that could otherwise be misread as a number, boolean or YAML keyword.

Why are some strings wrapped in quotes?

Values like "true", "123" or strings containing colons are quoted so the YAML round-trips back to the same JSON instead of being parsed as a different type.

No. The conversion runs entirely in your browser with JavaScript — your data is never sent to a server or stored.

Convert JSON to YAML in your browser

Paste any valid JSON and get clean, readable YAML with consistent two-space indentation. Nested objects, arrays and scalars are all supported, and strings that could be mistaken for numbers, booleans or YAML keywords are quoted automatically so the result round-trips safely.

The conversion happens entirely in your browser — your config and data are never uploaded or stored.
