JSON (JavaScript Object Notation) and YAML (YAML Ain't Markup Language) are two widely used data serialization formats for application configuration, APIs, and infrastructure files. JSON uses braces and brackets with strict syntax, while YAML uses indentation and is more human-readable. This tool converts between both formats.

Example: {"name": "edcilo", "active": true} converts to name: edcilo\nactive: true in YAML.
