About TestDataCraft
A free test data generator that runs entirely in your browser. Built for QA engineers, developers, testers, and students who need realistic test data quickly.
What is TestDataCraft?
TestDataCraft is a web-based test data generator that helps you create realistic, structured test data for your software projects. Whether you need JSON for API testing, CSV for database imports, SQL for seeding, or HTML/XML for other purposes, TestDataCraft generates it instantly.
Key Point: All data generation happens 100% in your browser. Your test data never leaves your device, and we don't store anything on our servers.
You can generate names, emails, phone numbers, addresses, UUIDs, dates, credit cards, and more—all formatted as realistic test data ready to use in your automation scripts, test cases, or development environments.
Who is TestDataCraft For?
QA Engineers & Testers
Create test data for functional testing, regression testing, and exploratory testing. Generate edge cases, valid/invalid data sets, and bulk test records.
Developers
Seed databases, mock API responses, populate dev environments, and test frontend components with realistic data during development.
Automation Engineers (SDET)
Generate test data for Selenium, Playwright, Cypress, or any automation framework. Export JSON/CSV and integrate directly into your test scripts.
Students & Learners
Practice SQL, learn data structures, build demo projects, or create portfolios with realistic-looking data without manually typing hundreds of records.
What Can You Generate?
Country-specific data: Generate India or USA-specific names, phone numbers, and addresses. Names and emails are intelligently linked (e.g., "aarav.sharma@gmail.com" matches the full name "Aarav Sharma").
Export Formats

Why Privacy-First Matters
TestDataCraft is designed with privacy as the foundation. All data generation happens entirely in your browser using JavaScript. This means:
- ✓No data transmission: Your generated test data never leaves your device
- ✓No storage on servers: We don't store, log, or track what you generate
- ✓No account required: Start generating data immediately, no signup needed
- ✓Works offline: Once the page loads, you can generate data even without internet
This approach means your sensitive test scenarios, data structures, and testing strategies remain completely private. We believe test data generation should be a tool you can trust.
Common Use Cases
API Testing
Generate JSON payloads for REST API tests, mock server responses, and validate endpoints with realistic data.
Database Seeding
Populate test databases with SQL INSERT statements or CSV imports for development and staging environments.
Test Automation
Create data sets for Selenium, Playwright, Cypress, or any automation framework. Export and import directly into scripts.
UI/UX Design
Fill mockups and prototypes with realistic names, addresses, and content instead of "Lorem Ipsum" or fake data.
Learning & Practice
Students can practice SQL queries, data analysis, or build demo projects with realistic-looking datasets.
Performance Testing
Generate large volumes of test data (up to 100,000 rows) for load testing and performance benchmarks.
