JSON → Java Class Generator – Free Online Utility

Generate Java POJO classes from JSON objects with Lombok and Jackson support.

JSON Input

Root Class

Lombok (@Data) Jackson Annotations

The generator recursively parses nested JSON objects and creates separate POJO classes for each, ensuring clean and modular code.

Jackson annotations like @JsonProperty allow you to map JSON field names (which might use snake_case) to Java field names (usually camelCase).

No. If you disable Lombok, the tool will generate standard Java fields. You will need to manually add getters and setters in your IDE.
