About the JSON to Java Class

Paste JSON and generate Java model classes: either modern Java 16+ records or classic POJOs with private fields plus getters and setters. Nested objects become their own types, arrays become List<T>, and Jackson @JsonProperty annotations plus the needed imports are added automatically.

Examples

Record output

{"id":1,"name":"Ada"}

Output

        Integer id,
        String name
) {}
