YAML Formatter

About YAML Formatter

The YAML Formatter beautifies, minifies, and validates YAML documents instantly. YAML is the preferred configuration format for Kubernetes, Docker Compose, GitHub Actions, Ansible, and dozens of DevOps tools. This formatter ensures your YAML is properly indented, syntactically valid, and easy to read — all processed client-side in your browser.

Key Features

• Beautify YAML — formats YAML with configurable indentation (2 or 4 spaces) for clean readability.
• Minify YAML — converts YAML to compact flow style for minimal file size.
• Validate YAML — detects syntax errors with precise error messages for quick debugging.
• Sort keys — optionally alphabetize all keys for consistent, diff-friendly output.
• Flow level control — choose between block style and flow style at different nesting depths.
• File upload & URL fetch — load YAML from files or remote endpoints.
