Automating Java DTOs

A **JSON to Java Converter** eliminates the tedious work of manually creating Java classes to match API responses. It analyzes the JSON payload and automatically generates the corresponding class hierarchy, including correct data types (e.g., `String`, `Integer`, `List`), ensuring your backend code aligns perfectly with external data sources.

How to Convert JSON to Java

  1. 1

    Paste JSON Payload

    Get your JSON object (e.g., from a REST API endpoint) and paste it into the editor area.

  2. 2

    Specify Class Name

    Enter the root class name in the standard `PascalCase` convention (e.g., `OrderDetails`).

  3. 3

    Integrate Code

    Copy the generated Java code into your project. It's ready to be used with libraries like **Jackson** or **Gson**.

Features

Java 8+ Compatible

Generates standard Java syntax compatible with modern JDKs (8, 11, 17, 21). Uses standard Collections (`List`, `ArrayList`).

Clean Structure

Nested objects are automatically extracted into static inner classes or separate definitions, keeping your file organized.

Robust Typing

We correctly map JSON types to Java types: `Double` for floats, `Integer` for ints, and `Boolean` for flags.
