What are JSON and YAML?
JSON (JavaScript Object Notation, RFC 8259) and YAML (YAML Ain't Markup Language, spec 1.2.2) are both human-readable data formats. They represent the same fundamental data — objects, arrays, primitives — with different syntax. JSON uses braces and brackets with strict quoting; YAML uses indentation and is more lenient.
When to use which
JSON dominates web APIs and inter-service communication. Compact, fast to parse, no ambiguity. YAML dominates configuration files — Kubernetes manifests, Docker Compose, GitHub Actions workflows, Ansible playbooks, GitLab CI, AWS CloudFormation, dbt, Hugo. The support for comments and the indentation-based readability tip the balance for human-edited configs.
Why convert between them?
Mixed-tool environments. Your CI generates JSON metrics but you need to commit YAML configs. Your API returns JSON but your deployment YAML reads from it. Some tools accept only one format. Conversion is the lubricant in modern DevOps pipelines.
