Frequently Asked Questions

Can I convert YAML with anchors and aliases?

Yes. Anchors (&name) mark a node for reuse; aliases (*name) reference it. When converting to JSON, all aliases are replaced with the referenced content inline - JSON has no equivalent shorthand.

Why does "yes" in YAML become true in JSON?

YAML 1.1 treated "yes", "no", "on", "off", "true", "false" as Booleans. YAML 1.2 restricted this to only "true" and "false". Many YAML parsers still use 1.1 semantics. If your YAML has "yes" as a string value, quote it explicitly: "yes".

How are multi-line YAML strings converted?

Literal block scalars (|) preserve newlines as-is. Folded scalars (>) join lines with a single space (replacing the newline). Both become JSON string values with appropriate newline characters in the output.

Does YAML support all JSON data types?

Yes - YAML strings, numbers, booleans, null, sequences (arrays), and mappings (objects) all map directly to JSON equivalents. YAML also supports ordered maps and binary data types that have no JSON equivalent and are handled as strings in the output.
