About This Tool

Generate Java POJO (Plain Old Java Object) classes from JSON data with Jackson @JsonProperty annotations. Perfect for enterprise Java developers working with REST APIs and Spring Boot.

The generator creates clean, compilable Java classes with proper field types (String, int, double, boolean, List<T>), constructors, and Jackson annotations for JSON serialization.

Supports nested objects as inner classes, arrays as List fields, and handles complex JSON structures. The output follows standard Java conventions and best practices.

All processing is done entirely in your browser. Your data never reaches any server, making it safe for confidential JSON payloads from enterprise APIs.

Save hours of boilerplate code writing. Essential for Spring Boot microservices, Android development, or any Java project that communicates via JSON APIs.
