Generate mock primitive data types, sample structured values, and realistic database column types for software testing. Flexible, developer-ready, and free online.
Use regex patterns to generate custom formatted data. Examples: [A-Z]3[0-9]3 for ABC123, \d4-\d2-\d2 for dates like 2024-01-15
Maximum: 5,000 rows

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.
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:
This makes the FakerBox tool ideal for building reliable test environments without exposing real production data.
Fake database column types generator results let you simulate data without depending on live databases.
Instead of writing manual entries, the data type generator produces values instantly.
Mock primitive data generator outputs resemble authentic system values like UUIDs or floats.
Use it for demos, prototypes, APIs, and database schema validations.
Pick from options like Boolean, Number, Float, Big Int, or UUID depending on your testing needs.
Click Generate to receive realistic random results such as:
Advanced users can apply regex patterns to control formats, for example ensuring UUIDs follow specific versions or number ranges are within defined limits.
Copy single results quickly, or export bulk outputs in CSV and JSON formats for integration into apps, tests, or research environments.
Use the data type generator to populate APIs and input fields with mock primitive data.
Simulate fake database column types for schema tests and migration exercises.
Teach database and coding concepts with sample structured data.
Generate safe random values for experiments, reports, or simulations.
Use dummy data in mockups or UX testing scenarios.
Generated sample structured data is fictional and must not replace actual system records. The FakerBox data type generator is intended for safe testing, education, and demos only.
It is a tool that produces mock primitive data such as booleans, numbers, floats, big integers, and UUIDs for testing and development.
Yes, the FakerBox tool works as a sample structured data generator for unit testing and schema demos.
Yes, it generates sample primitive values like true/false, integers, and floats.
It simulates realistic database values like big integers or UUIDs for safe testing.
Yes, regex allows you to format numbers, floats, or UUIDs to meet custom rules.
Yes, the FakerBox data type generator is completely free and unlimited.
Fake data types are widely used by developers, testers, database administrators, educators, and researchers for testing and learning purposes.
