JSON → YAML

Convert JSON to readable YAML with configurable indentation.

Private by design. Your input never leaves this browser. Conversions run locally on your device.

What this tool handles

Indentation of 2 or 4 spaces, or 0 for a compact flow style.
Keys can be sorted alphabetically instead of keeping their original order.
Repeated structures are written out in full; no anchors or aliases are emitted.
Strings that YAML would otherwise read as numbers, booleans or dates are quoted.

{"name":"Ada","active":true,"ports":[80,443]}

name: Ada
active: true
ports:
  - 80
  - 443
