About JSON to YAML Converter
JSON is fine for machines, but when a human has to maintain the config, YAML usually wins: no braces, no quotes everywhere, and you can add comments. This converter produces the YAML equivalent of whatever JSON you paste.
Common reasons people end up here: an API returns JSON but your
docker-compose.yml needs YAML, a webhook payload should
become a CI workflow, or a config file gets exported as JSON and you'd
rather review it as YAML.
The conversion runs entirely in the browser — nothing you paste is sent anywhere.
Frequently Asked Questions
Why convert JSON to YAML?
YAML is more human-readable than JSON for configuration: it supports comments, omits braces and quotes, and uses indentation for structure. Converting JSON to YAML is common when moving API data into docker-compose, GitHub Actions, Ansible or Kubernetes config files.
Can I choose the indentation of the output YAML?
Yes. Choose 2-space or 4-space indentation before converting. YAML requires spaces (never tabs) for indentation, and the converter guarantees valid output.
Does it support nested and complex JSON structures?
Yes. Nested objects, arrays, numbers, booleans and null values are all converted correctly to their YAML equivalents, keeping the exact same data structure.
Is the conversion done locally?
Yes. The conversion runs entirely in your browser with JavaScript. Your JSON is never sent to any server.
