How It Works
Select a data template (Users, Products, Blog Posts, Companies, etc.) and set how many objects to generate. Adjust complexity with the depth slider for nested objects. The tool uses Faker.js library to generate realistic data: names, emails, addresses, phone numbers, product names, prices, dates, and more. Preview the generated JSON with syntax highlighting. Copy to clipboard for quick use in code, or download as JSON file for testing APIs, mock servers, or development. Perfect for developers who need test data without manual typing. All generation happens in your browser.
