YAML to JSON Converter - Convert YAML ⇄ JSON Online

What are YAML and JSON?

YAML (YAML Ain't Markup Language) and JSON (JavaScript Object Notation) are both data serialization formats used for configuration files and data exchange.

YAML Characteristics:

  • Human-readable: Uses indentation instead of brackets
  • Comments supported: Lines starting with # are comments
  • Popular in DevOps: Kubernetes, Docker Compose, Ansible, GitHub Actions
  • Flexible: Supports complex data structures, anchors, references

JSON Characteristics:

  • Machine-readable: Uses braces and brackets for structure
  • No comments: Pure data format without comment support
  • Popular in APIs: REST APIs, web applications, configuration
  • Strict syntax: Requires quotes around keys and string values

Common Use Cases:

  • Kubernetes: Convert YAML manifests to JSON for programmatic manipulation
  • Docker Compose: Convert docker-compose.yml to JSON for parsing
  • CI/CD Pipelines: Convert GitHub Actions, GitLab CI, CircleCI configs
  • Configuration Management: Ansible playbooks, Helm charts
  • API Testing: Convert YAML test fixtures to JSON for APIs
