YAML Formatter Capabilities

The YAML formatter is designed to clean up and standardize YAML files, ensuring they are valid and readable. It serves as a powerful tool for developers and DevOps engineers.

Key Features

  • Fix indentation: Align nested objects, lists, and maps correctly so the YAML is valid.
  • Validate syntax: Detect missing colons, quotes, invalid keys, and structural issues.
  • Pretty-print: Convert messy or minified YAML into a readable, human-friendly format.
  • Convert between styles: Handle block style (| and >) and flow style ({} and []) consistently.

Advanced Support

  • Detect errors: Highlight broken sequences, improper nesting, duplicate keys, or invalid characters.
  • Optional minification: Compress YAML into a single line for compact storage.
  • Support complex structures: Correctly format deeply nested lists, dictionaries, and combinations.
