When converting hierarchical structures (Deeply nested PHP return array config files) and tabular or config formats (2D tabular rows (nested keys flattened via dot-notation)), our engine automatically flattens or unflattens dot-separated keys (such as address.city) and preserves numbers, booleans, arrays, and null values.
