Infers nested structures, arrays, missing fields and null from samples. Empty arrays use unknown types; Go / Java mixed types use any / Object. Python uses dataclasses (3.10+) with renamed JSON keys in field metadata (standard dataclasses do not automatically map JSON). Java generates private fields, a no-argument constructor and getters/setters, using static nested classes in single-file mode and separate classes in multi-file mode. Original JSON keys are kept in comments; configure special key mappings in your serialization framework.
