Features

Nested struct generation — extracts nested objects into clean top-level Go structs.
Int vs float64 inference — distinguishes whole numbers from floating-point values.

Frequently asked questions

Does it add omitempty tags?

Yes — toggle the Optional fields switch in the code generator panel to append omitempty to every json tag.

Is it safe for private API payloads?

Yes. Code generation runs entirely on your device.
