Frequently Asked Questions

Are JSON and YAML interchangeable?
YAML is a superset of JSON, so valid JSON is also valid YAML. However, YAML is more human-readable and is preferred for configuration files like Kubernetes manifests, GitHub Actions, and Ansible playbooks.
Does it support nested JSON objects?
Yes. Nested objects and arrays are fully supported and converted to their YAML indented block equivalents.
Can I convert YAML back to JSON?
This tool converts JSON to YAML only. For the reverse, look for our YAML to JSON converter in the developer tools section.
