What is random test data used for?

Random test data is used for unit tests, integration tests, database seeding, API testing, UI prototyping, and performance testing. It helps ensure applications handle a variety of real-world inputs correctly.

Can I customise the fields?

Yes. The generator includes common field types — name, email, phone, age, city, country, UUID, boolean, date, IP address, and more. Select the fields you want and set the number of rows.

Generating realistic random test data is essential for software development and testing. This tool creates structured fake data with configurable fields and exports it in the most common formats: JSON arrays, CSV spreadsheets, XML documents, YAML configuration, TSV files, and SQL INSERT statements ready to paste into a database.

Why Use Random Test Data?

Unit testing — verify that your code handles all kinds of valid inputs correctly
Database seeding — populate development and staging databases quickly
UI prototyping — see how your interface looks with realistic names, emails, and numbers
Performance testing — generate thousands of rows to test database queries under load
API testing — test endpoints with a variety of valid request bodies

Frequently Asked Questions

Is the generated data real?

No. All names, emails, phone numbers, and other values are randomly generated and not associated with real people. Do not use generated data to impersonate real individuals.

Can I generate more than 500 rows?

The maximum is 500 rows to keep the browser responsive. For large datasets, generate 500 rows multiple times or use a dedicated data generation library in your programming language.
