Frequently asked questions
When should I use YAML vs JSON?
YAML is more human-readable and great for config files. JSON is better for APIs and data exchange since it's more strict and widely supported.
Are comments preserved?
YAML comments are lost during conversion since JSON doesn't support comments.
