Why is indentation important in YAML?
YAML uses indentation (not brackets) to denote structure. A misplaced space can break parsing. This tool auto-fixes indentation.
Does it support YAML anchors and aliases?
Yes. Anchors (&) and aliases (*) are preserved and formatted correctly.
Is my data private?
Yes. All processing is in your browser. Sensitive config values are not uploaded.
