Share links encode data in the # anchor — never sent to a server.
Remember last edit
Optionally keep your last input locally; clear it with one click.
Why use YAML to JSON
Convert YAML to JSON
Turn YAML into JSON for APIs and programs.
Kubernetes & Docker Compose
Parse manifests, Compose files, CI configs and other common YAML.
Indentation-Safe Parsing
Restores hierarchy by indentation; maps/sequences/scalars map accurately.
Comment-Loss Notice
When # comments are detected you get a clear notice, so nothing seems silently kept.
Runs Locally — No Upload
Conversion runs entirely in your browser; data is never uploaded or stored.
