YAML ↔ JSON Converter

YAML is a human-oriented serialization format with indentation, comments, anchors, and flexible scalar syntax. JSON is stricter and easier for many APIs to parse. A converter makes the data model visible across the two formats, but it cannot preserve every YAML feature: comments, aliases, tags, and implicit types may be lost or normalized during conversion. Review the result as data, not only as text.

Validate indentation and inspect scalars that could change type, such as dates, booleans, numeric-looking strings, and null values. Check duplicate keys, aliases, and untrusted tags before passing YAML to a parser. For configuration, compare the converted structure with the service schema and run a dry-run validation. Keep secrets out of browser tools when possible, and never assume that successful parsing means the configuration is safe to deploy.

Infrastructure files often contain credentials, hostnames, and internal topology. Converting them locally avoids sending that context to a remote formatter and provides immediate feedback while editing. Browser parsing is still not a policy engine: production validation should use the same parser version, schema, and admission checks as the deployment pipeline. Preserve the original file and review meaningful type changes before committing the converted output.
