JSON vs YAML
JSON (JavaScript Object Notation) is a strict, widely-supported data format. It's the default for APIs, configuration files, and data exchange. Every value must be explicitly typed — strings require quotes, no comments allowed, no trailing commas.
YAML (YAML Ain't Markup Language) is a human-friendly superset of JSON. It uses indentation instead of braces, supports comments, multiline strings, and anchors/aliases. YAML is commonly used for configuration files (Docker Compose, Kubernetes, CI/CD pipelines, Ansible).
Convert between the two formats in real time using the yaml library (full YAML 1.2 spec). Works offline once loaded.
