Dummy Data Generator is a Chrome extension designed to facilitate the quick generation of realistic dummy data tailored for Java and TypeScript classes. This free tool significantly enhances the efficiency of developers by enabling them to produce sample data for unit testing, prototyping, and mock API design in just seconds. With automatic detection of the programming language, it ensures users receive valid and readable outputs with a single click.

The extension supports a variety of output formats, including Java classic objects, Java with Lombok builder, and TypeScript JSON-style objects. It also features custom field recognition for specific data types like email and age, ensuring the generated values are realistic rather than mere placeholders. Users can easily copy the generated data to their clipboard and have the option to generate multiple objects simultaneously, making it an excellent resource for backend developers, frontend mock data setup, and rapid prototyping.
