YAML Formatter

Beautify and validate YAML. Format config files for readability.

What is YAML?

YAML (YAML Ain't Markup Language) is a human-readable data format. Used for config files (Docker, Kubernetes, GitHub Actions), it uses indentation and minimal syntax.

What is it used for?

  • Config files: docker-compose.yml, .github/workflows
  • Kubernetes: Manifests and Helm charts
  • CI/CD: Pipeline definitions
  • Data: Alternative to JSON when readability matters

How it works

Beautify reformats with consistent indentation. Minify compacts. Validate checks syntax. Uses js-yaml. All processing in your browser.
