Custom Test Data Generator Tool

Generate custom CSV and JSON test data with unlimited columns and data types. Perfect for database testing, software development, API testing, and data analysis. Create realistic fake data including names, emails, addresses, phone numbers, financial data, and more for your testing needs.

What Is a Fake Data Type Generator?

A fake data type generator is a tool that produces mock primitive values and structured sample data for development and QA. It works as both a mock primitive data generator and a sample structured data generator. Developers and testers can use it to:

  • Generate mock primitive values for unit testing
  • Create structured datasets for prototyping or demos
  • Simulate fake database column types for schema testing
  • Export sample structured data for use across platforms

This makes the FakerBox tool ideal for building reliable test environments without exposing real production data.

Why Use Mock Primitive Data?

Safe for Testing

Fake database column types generator results let you simulate data without depending on live databases.

Saves Development Time

Instead of writing manual entries, the data type generator produces values instantly.

Realistic Results

Mock primitive data generator outputs resemble authentic system values like UUIDs or floats.

Flexible Applications

Use it for demos, prototypes, APIs, and database schema validations.

How to Generate Sample Data Types?

Choose Your Data Fields

Pick from options like Boolean, Number, Float, Big Int, or UUID depending on your testing needs.

Create Sample Primitive Values

Click Generate to receive realistic random results such as:

  • Boolean: true
  • Number: 2345
  • Float: 12.4567
  • Big Int: 82937498237498234
  • UUID: 550e8400-e29b-41d4-a716-446655440000

Regex Options

Advanced users can apply regex patterns to control formats, for example ensuring UUIDs follow specific versions or number ranges are within defined limits.

Download Outputs

Copy single results quickly, or export bulk outputs in CSV and JSON formats for integration into apps, tests, or research environments.
