Switch between JSON and YAML in either direction. Paste JSON to get YAML, or YAML to get JSON, with parse errors shown clearly. Useful for Kubernetes manifests, CI config, and app settings. YAML anchors and custom tags may not round-trip perfectly; standard mappings and lists convert cleanly. Nothing is uploaded.
