POJO Tools - Generate Plain Old Java Objects from JSON, XML, YAML

Generate Plain Old Java Objects (POJOs) with Our Comprehensive POJO Tools

Our POJO Tools generator is a powerful utility designed to create Plain Old Java Objects (POJOs) and equivalent data structures in multiple programming languages from JSON, XML, and YAML data. Whether you're a Java developer, working with TypeScript, Python, C#, Go, Dart, JavaScript, or Objective-C, this tool helps you quickly generate clean, well-structured classes and interfaces.

No more manually writing boilerplate code for data classes. Our comprehensive generator supports 8 different programming languages and 3 input formats, making it the perfect tool for API development, data modeling, and rapid prototyping across multiple technology stacks.

Best Practices: Follows language-specific coding conventions and best practices

Frequently Asked Questions

What programming languages are supported?

Our POJO Tools generator supports 8 programming languages: Java, TypeScript, Python, C#, Go, Dart, JavaScript, and Objective-C. Each language generates code following its specific conventions and best practices.

Can I customize the generated code?

Yes! You can customize the generated code by toggling getters, setters, toString(), equals(), and hashCode() methods. For Java, you can also enable Lombok annotations to reduce boilerplate code.

What input formats are supported?

The generator supports three input formats: JSON, XML, and YAML. It automatically detects the format and extracts fields accordingly, handling nested objects and arrays intelligently.

How does the type detection work?

The generator automatically detects data types from your input (string, number, boolean, array, object) and maps them to appropriate types in the target programming language. For example, JSON strings become String in Java, string in TypeScript, and str in Python.

Question not found

Absolutely! The generated code follows best practices and coding conventions for each programming language. It's production-ready and includes proper error handling, type safety, and follows language-specific patterns.

Does the generator handle nested objects?

Yes! The generator intelligently handles nested objects and arrays. It extracts fields from all levels of nesting and creates appropriate type definitions for complex data structures.

What is Lombok support?

Lombok is a Java library that reduces boilerplate code. When enabled, the generator creates Java classes with @Data, @NoArgsConstructor, and @AllArgsConstructor annotations, automatically generating getters, setters, toString(), equals(), and hashCode() methods.
