Frequently asked questions

Which YAML features are supported?
Standard block-style YAML: mappings, sequences, scalars (string, number, boolean, null), 2-space indentation, and inline flow collections. Anchors and tags are not supported.
Why use YAML over JSON?
YAML is easier to read and edit by humans (comments, no trailing commas, less punctuation). Popular for configuration files like docker-compose and Kubernetes manifests.
Does it preserve key order?
Yes. JavaScript object iteration preserves insertion order for string keys, so the JSON key order is maintained in the YAML output.
Is my data uploaded anywhere?
No. Everything runs locally in your browser. No network calls are made for conversion.
