Paste a JSON object and get YAML you can drop into a config file. Top-level keys become YAML keys, strings are quoted safely and nested objects or arrays are kept as an inline JSON value so nothing is silently lost. The input must be an object rather than an array or a bare primitive.
🔒 Your file is processed locally in your browser whenever supported. This tool runs entirely on your device — nothing you type or upload is sent to a server, logged, or stored.
No. This converter targets flat configuration objects; a nested object or array is emitted as an inline JSON value under its key. That preserves the data, but a full YAML library may produce prettier nesting.
Not directly. Wrap the array in an object, for example {"items": [...]}, or use a full YAML converter if the document must remain a top-level array.
Quoting prevents YAML from reinterpreting values such as yes, no, on, off or numbers as booleans and numbers. Embedded double quotes are escaped.
No. Parsing and conversion happen entirely in your browser.
