Frequently asked questions
How do I convert a YAML config file to JSON?
Paste your YAML into the input panel and the equivalent JSON is generated immediately, preserving nested objects, arrays, booleans, nulls, and numbers. Switch direction to convert JSON back into YAML.
Does this tool support Kubernetes and GitHub Actions YAML files?
Yes. It parses standard YAML syntax used in Kubernetes manifests, Helm charts, and GitHub Actions workflows, converting nested structures, lists, and scalar types into matching JSON.
Is my YAML data safe to paste into this converter?
The conversion runs entirely in your browser, so your YAML or JSON content is not sent anywhere to process the conversion.
Can this tool validate whether my YAML syntax is correct?
Yes. If the YAML has a syntax error, the parser surfaces it instead of producing a conversion, which makes the tool useful as a quick YAML validity check before converting.
