ConversionTop-level scalars come first, nested objects become [sections] (deeper levels use dotted sections). Scalar arrays are written as repeated key[] lines; more complex arrays fall back to a JSON string with a notice.

Why use JSON to INI

Sections drawn for you

Nested objects become [sections], with deeper levels as dotted [a.b] sections — the hierarchy stays obvious.

Classic-format compatible

The output is the INI dialect that system tools, games and legacy software all recognize.

Arrays with a convention

Scalar arrays are written as repeated key[] lines (the npm ini convention); complex arrays fall back to a JSON string with a notice.

Special values quoted

Values containing semicolons, hashes or surrounding spaces are quoted so comment markers never truncate them.
