How to use JSON to YAML

Create a YAML configuration draft from JSON without manually changing braces and quotes. Values are serialized by the YAML library; ambiguous string values are quoted where required.

  1. Paste the JSON data to represent as YAML.
  2. Select Run tool to serialize a standard YAML document.
  3. Review the result, then copy it or download the generated file.

Good to know

  • Up to 100,000 input characters, 10,000 values, and 40 nesting levels. Standard JSON numbers use JavaScript precision; duplicate keys retain their last value.
  • Original JSON whitespace is discarded. Application-specific YAML tags, comments, and schemas cannot be inferred.

Common questions

Will a string such as true become a boolean?

The serializer quotes strings when necessary to preserve their string type in the core schema.
