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.
