Frequently Asked Questions

What json tags does it generate?

Each field gets a `json:"originalKey"` tag matching the exact JSON key, so encoding/json round-trips correctly even though Go field names are PascalCased.

How are null values handled?

A null value produces interface{}, since Go has no built-in optional/nullable primitive types — you'd typically swap in a pointer type or a null-aware type based on your use case.

How are nested objects handled?

Each nested object gets its own named struct, derived from its key, rather than an anonymous inline struct.

Is my data uploaded anywhere?

No — generation runs entirely in your browser.
