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.

JSON
JSON (JavaScript Object Notation) is a lightweight, text-based data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is based on a subset of JavaScript syntax but is language-independent.
Autonomous Driving
Autonomous Driving is a technology that enables vehicles to navigate and operate without human intervention by using a combination of sensors, artificial intelligence, and control systems. It encompasses various levels of automation defined by SAE International, ranging from Level 0 (no automation) to Level 5 (full automation), where the vehicle can handle all driving tasks in all conditions without any human input.
Barcode
Barcode is a machine-readable representation of data using patterns of parallel lines (1D) or geometric patterns (2D) that can be quickly scanned to retrieve encoded information.
Bearer Token
Bearer Token is an access token type used in HTTP authentication where the client presents a token to access protected resources. The term 'bearer' means that any party holding the token can use it to access the resource, without needing additional proof of identity.
JSON Schema
JSON Schema is a vocabulary that allows you to annotate and validate JSON documents. It describes the structure, constraints, and documentation of JSON data, enabling automated validation and documentation generation.
