Frequently Asked Questions
Can it handle nested JSON objects?
Yes! Nested objects are automatically converted to inner static classes, preserving the full object hierarchy.
Does it support Lombok annotations?
Yes, enable the "Use Lombok @Data" option to generate clean POJOs with @Data, removing boilerplate getters and setters.
What Java version is the generated code compatible with?
Java 8 and above. The generated code uses standard Java syntax compatible with all modern Java versions.
Do I need Gradle or Maven dependencies?
Only if you enable Lombok or Jackson options — you'll need the corresponding dependencies in your build file. The generated code shows which imports are needed.
