About Synthetic Data Generator

The Synthetic Data Generator is a powerful, client-side tool designed for developers, QA engineers, and data scientists who need to create high-quality mock data for their applications. Unlike basic random string generators, this tool produces context-aware data across multiple categories including Personal (names, emails, addresses), Business (companies, job titles), Finance (credit cards, IBANs), and Technical (IPs, MAC addresses). It runs entirely in your browser, ensuring that your data generation process is fast, private, and secure. You can customize the number of rows, select only the specific fields you need, and export the result instantly in popular formats like JSON, CSV, SQL INSERT statements, or TypeScript interfaces. Whether you are seeding a local database, testing a UI with realistic content, or mocking an API response, this tool provides a flexible and efficient solution.
