JSON to YAML Converter

YAML ("YAML Ain't Markup Language") is a human-readable data serialization format designed for configuration files where indentation defines structure instead of brackets. It first appeared in 2001 as a more readable alternative to XML, and has since become the dominant format for DevOps tooling: Kubernetes manifests, GitHub Actions workflows, Docker Compose files, Ansible playbooks, OpenAPI specs, and most CI configurations. Compared to JSON, YAML supports comments (#), multi-line strings, anchors and aliases for DRY config, and a wider type system. YAML 1.2 is technically a superset of JSON — so converting from JSON to YAML is loss-free, while the reverse can require care around YAML-specific features. This converter handles JSON → YAML with configurable indentation. Need the reverse? Use the YAML to JSON tool. Validating raw JSON first? Run it through the JSON Formatter.
