YAML to JSON
YAML is the config language behind CI pipelines, Kubernetes, and Docker Compose — files that routinely hold tokens and credentials, so converting one online means uploading them. This reads a YAML document as JSON in your browser. Note that comments and anchors don't survive the trip — JSON has neither. YAML scalars are parsed into JSON values, so quote identifiers, version strings, and other number-like text if they must remain strings.
