JSON to YAML: convert JSON into a readable YAML document
Convert a JSON value into a YAML document (block style, no line folding), for config files, Kubernetes manifests, GitHub Actions or docs that humans edit. Up to 100 KB of JSON. Use when a tool or person wants YAML; for the reverse use yaml_to_json. Invalid JSON is a 400, uncharged.
