FAQ

Should I use omitempty or pointers?

Both — pointers + omitempty is the most flexible combo: zero-value fields are serialized for value types (with omitempty they'd vanish), and pointer fields with omitempty only serialize when set.

Why are my numbers int64?

JSON numbers are double-precision floats — the tool picks int64 for whole numbers, float64 otherwise. If your numbers fit in int32, hand-edit.

Will it work offline?

Yes.
