What YAML features are supported?

Basic YAML with nested mappings, sequences, scalars (string, number, boolean, null), and quoted strings. Multi-line literals (|, >), anchors (&), and references (*) are not supported.

Is my data uploaded anywhere?

No. All conversion happens locally in your browser with no server round-trip.

How are YAML types inferred?

Unquoted scalars are inferred: 'true'/'false' → boolean, 'null'/'~' → null, digits → number, everything else → string. Use quotes to force string type for values like '3.14' or 'true'.

What indentation does JSON-to-YAML use?

2-space indentation, with sequences rendered in block style (- item). Flow style ([a, b]) is not used; this maximizes readability and diff-friendliness.

Can I convert Kubernetes manifests?

Yes, as long as they use only supported features. Multi-document YAML (--- separators) is not supported; convert each document separately.

Why does my YAML fail to parse?

Common causes: tabs for indentation (YAML requires spaces), missing space after colon, unsupported anchors/multi-line literals. Check the error message for the line number.
