YAML / JSON

Convert a YAML mapping into pretty JSON, or serialize JSON as YAML. Alias expansion is capped so one anchor cannot multiply a node without bound.

Example: Service manifest

service: billing
active: true
seats: 3
ports:
  - 8080
  - 8081

A common error

A tab used as indentation, or JSON with a trailing comma in the JSON-to-YAML direction, is rejected. Review timestamps before replacing a source file.
