Features

Based on quicktype engine, this tool converts JSON data to Java POJO classes with Lombok, Jackson, and other options.

Options

Package name: The package declaration in generated code, defaults to com.example.
Root class name: The root type name to generate, defaults to Root.
Array type: Controls the Java type of array fields (List or ArrayList).
Lombok: When checked, uses Lombok annotations (@Data, @Builder, etc.) to simplify code.
