Frequently Asked Questions

Is this JSON to YAML converter free?
Yes, 100% free. No account, no limits, and nothing is uploaded — the conversion runs entirely in your browser.
Why would I convert JSON to YAML?
YAML is more human-readable than JSON, making it popular for configuration files (Docker Compose, Kubernetes, CI/CD pipelines). Converting JSON to YAML helps you author or review configs more easily.
Does the converter preserve all JSON data types?
Yes. Strings, numbers, booleans, nulls, arrays, and nested objects are all converted accurately using js-yaml.
Are my files safe?
All processing runs locally in your browser. Nothing is sent to any server.
Does it work on mobile?
Yes, it works on all modern browsers including mobile Safari and Chrome on iOS and Android.
