Normalizing YAML
YAML is whitespace-sensitive, so inconsistent indentation is a common source of bugs. This formatter parses your YAML (validating it and reporting any syntax errors), then re-serializes it with consistent indentation and normalized structure — flow collections become block style and keys keep their original order. All parsing happens locally in your browser.
