What is YAML to JSON Converter?
YAML to JSON is a developer tool that converts YAML (YAML Ain't Markup Language) data into JSON (JavaScript Object Notation) format.
YAML is popular in DevOps config files (Docker Compose, Kubernetes manifests, GitHub Actions workflows), and sometimes you need the equivalent JSON for APIs, scripts, or tools that only accept JSON. This converter handles key-value pairs, nested maps, sequences (arrays), inline syntax, and common YAML scalar types like booleans, numbers, and null.
