Format Details
YAML
YAML (YAML Ain't Markup Language) is a human-friendly data serialization format designed to be more readable than JSON or XML for configuration files and structured data. It uses indentation and minimal punctuation to represent nested data structures, sequences, and mappings in a way that closely resembles natural language. YAML is the native configuration format for Kubernetes, Docker Compose, GitHub Actions, Ansible, and countless other modern developer tools.
JSON
JSON (JavaScript Object Notation) is a lightweight, human-readable data interchange format derived from JavaScript object literal syntax. It natively supports objects, arrays, strings, numbers, booleans, and null, allowing it to represent arbitrarily nested data structures. JSON has become the universal standard for REST API responses, configuration files, and data interchange on the web, with native parsing support in virtually every programming language.
