Frequently asked questions
What’s the difference between YAML and JSON?
They represent the same data; YAML uses indentation and is friendlier to write by hand, while JSON uses braces and is the standard for APIs.
Does it keep my data types?
Yes — strings, numbers, booleans, lists, and nested objects are preserved across the conversion.
Why does my YAML fail to convert?
YAML is indentation-sensitive; inconsistent spacing or tabs are the most common cause of parse errors.
Is it private?
Yes — conversion runs in your browser with no uploads.
