FAQ

What is the difference between JSON and YAML?

JSON uses braces and brackets with strict syntax. YAML uses indentation-based formatting which is more human-readable. Both represent the same data structures but YAML is popular in configuration files (e.g., Kubernetes, Docker Compose).

What formats are supported?

This tool converts between JSON and YAML. Paste valid JSON to get YAML, or paste valid YAML to get JSON. The tool will show error messages if the input is invalid.

Is my data safe?

Yes. All conversion runs locally in your browser using the js-yaml library. No data is sent to any server.

Security: All processing runs locally in your browser. No data is sent to any server.
