About JSON to Java

Paste JSON and get Java types instantly — records for modern Java or classic POJO classes with getters, both with nested objects mapped to their own types and arrays to lists.

Handy for modeling REST API responses in Spring or Jackson/Gson projects. Generation runs entirely in your browser — your payload is never uploaded.
