About the YAML / JSON Converter

Pick a direction, paste your text, and the converter turns YAML into JSON or JSON into YAML. It converts as you type and shows a clear message if something cannot be parsed.

The YAML reader supports the common building blocks you will see in most config files: nested maps, lists, quoted and plain strings, numbers, booleans, null, comments starting with #, and inline flow style like [1, 2, 3] and {a: 1}. Very advanced YAML features such as anchors, aliases, tags and multi-document files are not supported.

Is anything uploaded? No. All conversion happens in your browser, so your data stays on your device.
