Format and validate YAML online

The formatter parses your YAML before rewriting it with consistent two-space indentation, so syntax problems are shown before you copy or download a configuration file.

Formatting tips

• Use spaces instead of tabs
• Align nested keys consistently
• Quote values when their type could be ambiguous
