Mock Data Generator

The tool supports three export formats: JSON for API testing and JavaScript applications, CSV for spreadsheets and database imports, and SQL INSERT statements for direct database population. You can copy the generated data to your clipboard or download it as a file.

No, all generated financial data is completely fake and cannot be used for real transactions. Credit card numbers follow the Luhn algorithm format to appear valid but are not connected to any real accounts. Social Security Numbers are generated with formats that avoid real SSN patterns. This data is safe to use in test environments.

The seed option allows you to generate the same data set every time by providing a specific number. This is useful when you need consistent test data across multiple runs or when sharing test scenarios with team members. Leave it empty for random data each time, or set a specific value for reproducible results.

You can generate between 1 and 1,000 rows of data in a single batch. For datasets up to 20 rows, the tool also displays a preview table so you can visually verify the generated data before exporting. All processing happens client-side in your browser.

No, all data generation happens entirely in your browser using JavaScript. No data is sent to any server. The generated data exists only in your browser session until you export or copy it. This makes the tool safe to use even when generating sensitive-looking test data.
