Converts data between JSON (JavaScript Object Notation) and YAML (YAML Ain't Markup Language) formats. Both formats represent the same data structures but have different syntax — JSON uses braces and quotes while YAML uses indentation.
JSON objects become YAML mappings with key: value syntax, no quotes needed for simple strings.
Inputs
Result
JSON uses curly braces, square brackets, and quoted strings. YAML uses indentation and colons. YAML is generally more human-readable and supports comments; JSON is more widely supported in APIs and configuration files.
