#What this tool does

Paste YAML, get pretty-printed JSON with correct type mapping. Strings, numbers, booleans, arrays, nested objects, and null values are all preserved. Multi-document YAML (---) converts to an array of JSON objects.

All conversion runs client-side in your browser. Nothing is sent to a server.

#When to use this

  • Sending YAML configs to REST APIs that expect JSON
  • Manipulating configs with jq or JSON.parse() without a YAML library
  • Debugging deeply nested YAML — JSON's explicit braces make structure unambiguous
  • Feeding Kubernetes manifests into cloud CLI tools that only accept JSON

Watch out for YAML 1.1 boolean coercion: country: NO becomes "country": false unless quoted. Validate your YAML first.

#Related tools

Need the reverse? JSON to YAML. Validate syntax with the YAML validator, or format with the YAML formatter. For API specs, try the OpenAPI validator.
