Frequently Asked Questions
Which YAML features are supported?
Standard mapping/list structures and basic scalar types (string, number, boolean, null) are supported. Advanced YAML features like anchors/aliases (&/*), multi-document (---), and flow style ({a: 1}) are not currently supported.
Why does indentation matter?
Unlike JSON, YAML expresses hierarchy through whitespace indentation instead of braces. Use spaces (not tabs) and stick to a consistent 2-space indent.
