YAML Formatter

What is YAML?

YAML (YAML Ain't Markup Language) is a human-friendly data serialization language commonly used for configuration files and data exchange. It's widely used in DevOps tools, CI/CD pipelines, Docker, Kubernetes, and many modern applications.

Why Use a YAML Formatter?

YAML is sensitive to indentation and formatting. Our YAML formatter helps you:

• •Validate YAML syntax and catch indentation errors
• •Standardize YAML formatting across your projects
• •Ensure consistent indentation levels
• •Clean up messy YAML from various sources
• •Process YAML instantly in your browser

How to Use

1. Paste your YAML content into the input area
2. Select your preferred indentation (2 or 4 spaces)
3. Click Format to clean and beautify your YAML
4. Copy the formatted output with one click

Best Practices

YAML uses indentation to represent structure - always use spaces, never tabs. Our formatter automatically handles this for you, ensuring your YAML is properly formatted and valid.

Privacy & Security

Your YAML data is processed entirely in your browser. Nothing is uploaded to our servers, keeping your configuration files and sensitive data completely private.
