How to use the JSON to YAML converter

Paste JSON on the left — for example package.json, an API response or a config.
YAML appears on the right instantly; choose the indent, key sorting and list style.
Copy the YAML or download it as a .yaml file.

YAML is used by Docker Compose, Kubernetes, GitHub Actions, Ansible and many static-site generators. Strings that look like numbers, dates or booleans are quoted automatically so they keep their type. For the opposite direction use our YAML to JSON converter.
