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.
