Parse YAML configurations and convert them into standardized JSON format. Convert Kubernetes configs, GitHub Actions workflows, and Docker Compose files into programmable JSON objects.

Key capabilities:

  • Configurable JSON output indentation (2 spaces, 4 spaces, or compact minified)
  • Syntax error diagnostics detecting indentation errors and invalid YAML syntax
  • Direct client-side execution in your browser with zero network transmission
Tips:
  • Ensure your YAML uses consistent 2-space indentation without tab characters before converting.
  • Use 2-space JSON formatting for human readability or 0-space minification for production APIs.
  • Click the Copy button to immediately paste the resulting JSON into your application codebase.
