Does this support all JSON data types?

Yes. Strings, numbers, booleans, null, nested objects, and arrays are all converted to their YAML equivalents. Strings requiring quoting (e.g. those starting with special characters) are automatically quoted.

Can I use the output in Kubernetes or Docker Compose?

The YAML output follows standard YAML 1.2 syntax and is compatible with Kubernetes manifests, Docker Compose files, and most YAML-consuming tools.

What indentation does the output use?

The output uses 2-space indentation, which is the most widely adopted convention in the YAML ecosystem.

JSON to YAML converts any valid JSON — objects, arrays, strings, numbers, booleans, and null — into equivalent YAML syntax. Objects become key-value pairs, arrays become dash-prefixed lists, and special characters in string values are properly handled. No library is used; the conversion is implemented directly for full browser compatibility.
