How does the tool handle nested objects?
The generator creates separate type definitions for each nested object. For example, if your JSON has an address object inside a user object, it will create both User and Address types with proper references.
What about arrays of objects?
Arrays of objects are handled by creating a type for the array items. The tool analyzes the first item to determine the structure and generates appropriate array types like User[] in TypeScript or []User in Go.
Does it support nullable types?
Yes, null values in JSON are converted to appropriate nullable types for each language - null in TypeScript, *Type or interface{} in Go, Optional in Python, and nullable reference types in C#.
Can I customize the root type name?
The default root type name is Root. You can easily rename it in the generated code, or the tool will use meaningful names based on the JSON structure when possible.
