JSON vs YAML

Both formats represent data the same way, but with different syntax:

JSON uses strict punctuation with braces and brackets, perfect for APIs and machine parsing.

YAML uses indentation and clean syntax, perfect for configuration files and human readability.

This converter handles complex nested structures, arrays, strings, numbers, booleans, and null values in both directions.
