Frequently asked questions
Why convert JSON to YAML?＋
YAML is far more readable for config files such as Docker, Kubernetes and CI pipelines, so this helps when moving JSON config into those formats.
Does it preserve my data types?＋
Yes — strings, numbers, booleans, arrays and nested objects all map to their YAML equivalents.
Is anything sent to a server?＋
No — it all runs locally in your browser.
