JSON to YAML converter

Converts JSON to YAML with safe quoting and configurable indentation - the output round-trips back to the same JSON values.

What this does

Parses your JSON, then serializes it as YAML with js-yaml's dumper - arrays, nested objects and multiline strings are all handled, with configurable indentation.

Round-trips correctly

The generated YAML is produced by the same library used to parse it back, so converting to YAML and back to JSON reproduces the original values for every JSON type this tool accepts.
