JSON to Go
Convert JSON objects to Go type definitions, interfaces, or classes automatically.
About JSON to Go
Generate Go structs from JSON with proper json tags. The converter creates idiomatic Go structs with exported field names (PascalCase) and json struct tags for accurate marshalling/unmarshalling. Nested objects become separate structs. Go's encoding/json package uses these tags to map JSON field names to Go field names.
FAQ
How are null values handled?
Null values in JSON are mapped to nullable/optional types in the target language. In TypeScript: field: Type | null. In Go: *Type (pointer). In Python: Optional[Type]. In Java: Optional or @Nullable annotation. If a field is null in your sample JSON, consider providing a more complete sample where the field has a real value so the type can be accurately inferred.
