JSON Input
YAML Output

Keep strings distinct from numbers in YAML

Frequently Asked Questions: When do strings need quoting in the YAML output?

The code "001" stays a string, false stays a boolean, and null stays null. Indentation changes the layout, not these values. Keys, arrays and nested objects are serialized from the parsed JSON; comments cannot be recovered because JSON has no comments.

JSON is parsed with JavaScript JSON.parse. Numbers beyond the safe integer range can lose precision: use quoted strings for identifiers. This converter does not evaluate templates or test a Kubernetes, Compose or other application-specific configuration.

Input

{"code":"001","enabled":false,"items":[1,null]}

Formatted Output

code: '001'
enabled: false
items:
  - 1
  - null
