FAQ

Frequently asked questions

What is the difference between YAML and JSON?

JSON is strict and common in APIs. YAML is more human-readable but indentation-sensitive.

Can comments be preserved?

JSON does not support comments, so comments may be lost during conversion.

Why does YAML indentation matter?

Indentation defines structure in YAML, so small spacing changes can alter the result.

Are my inputs sent to a server?
