What is the difference between JSON and YAML?

JSON uses braces and brackets with strict syntax rules. YAML uses indentation and is designed to be more human-readable. Both represent the same data structures — objects, arrays, strings, numbers, booleans, and null.

Does this handle nested objects and arrays?

Yes. The converter recursively processes any depth of nesting. Arrays become YAML sequences with dash prefixes, and nested objects use indented key-value pairs.

Is this tool free to use?

Yes. This tool runs entirely in your browser with no account required. Your data never leaves your device.

Can I convert YAML back to JSON?

Yes. Toggle the direction selector to switch between JSON-to-YAML and YAML-to-JSON modes. The tool parses YAML input and outputs formatted JSON.

Does this work on mobile?

Yes. The tool is fully responsive and works on any device with a modern browser. You can paste JSON or YAML from other apps, convert it, and copy the result back. No installation or app download required.
