Frequently asked questions

What is the inline level setting?

It controls at what nesting depth YAML switches from expanded (one key per line) to inline ({key: value}) notation. Higher values mean more expanded output. Default is 10, which keeps most structures expanded.

Does it handle arrays correctly?

Yes. JSON arrays become YAML sequences with dash notation (- item). Nested arrays and mixed types are fully supported.

What about special YAML values?

JSON null becomes YAML null, true/false stay as booleans, and numeric strings are properly quoted if needed to prevent YAML type coercion.
