YAML Formatter

Format and validate your YAML files for better structure and readability.

How to Use the YAML Formatter

This tool helps ensure your YAML (YAML Ain't Markup Language) files are well-structured and properly indented. Given that YAML is sensitive to whitespace, a good formatter is essential for avoiding syntax errors.

  1. Paste Your YAML: Enter your YAML content into the text area.
  2. Format: Click "Beautify / Format". The tool will apply standard 2-space indentation and clean up the structure. (Note: This is a basic formatter and may not catch all YAML syntax errors).
  3. Copy: Use the "Copy" button to get your formatted YAML.

Frequently Asked Questions (FAQ)

Q: What is YAML used for?

A: YAML is a human-readable data-serialization language. It is commonly used for configuration files and in applications where data is being stored or transmitted. It's a popular choice in tools like Docker (docker-compose.yml) and Kubernetes.

Q: Why is indentation so important in YAML?

A: Unlike JSON, which uses braces, YAML uses indentation to denote structure and nesting. Even one incorrect space can lead to a parsing error, which is why a reliable formatter is so helpful.
