About JSON to TypeScript
Automatically generate TypeScript interfaces from JSON data. The converter infers types from values: strings become string, numbers become number (or number for floats), booleans become boolean, arrays become Array
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.
