Frequently asked questions

What types does it infer?

string→string, whole numbers→int, decimals→float64, true/false→bool, null→interface{}, arrays→[]T, and objects→nested structs.

Is the output ready to compile?

It is a strong starting point. Review numeric widths, optional fields, and pointer usage — inference is intentionally conservative.

How are nested objects handled?

Each nested object gets its own named struct type, referenced by field, with matching json tags for the original keys.
