How to Generate Mock Data in 3 Simple Steps
- Define Your Fields Name your columns (e.g., user_email, transaction_id) and select the data type from our extensive library. We support everything from Credit Cards and IPv4 addresses to Full Names and Dates.
- Set Your Volume Whether you need a single row for a sanity check or 10,000 rows for bulk load testing, just set the count and click generate.
- Export & Go Preview your data instantly in a clean table format, then download it in your preferred structure: JSON, CSV, SQL, XML, or Excel (XLSX).
Why Use This Tool?
100% Free to Use No hidden paywalls for basic data generation. Create the datasets you need for your QA, staging, or demo environments without touching your budget.
GDPR & Privacy Safe Stop copying production data. This tool generates “Synthetic Data”—information that looks 100% real but belongs to no one. Test safely without risking PII leaks or compliance violations.
Smart Context AI Unlike random text generators, our tool maintains logic. If the City is “New York,” the State will be “NY,” and the Zip Code will match.
Massive Time Savings Eliminate the tedious manual entry of “Test User 1,” “Test User 2,” etc. Generate thousands of unique, formatted records in a single click.
Perfect For…
- Database Seeding: Populate SQL databases with bulk data to test query performance and indexing.
- API Validation: Generate complex JSON objects to test API endpoints and payload handling.
- UI Stress Testing: Fill forms with long strings, special characters, and edge cases to test UI resilience.
- Demo Environments: Create realistic-looking dashboards for client demos without exposing sensitive real-world data.
Frequently Asked Questions (FAQ)
Is this Test Data Generator completely free? Yes. This tool is 100% free to use. You can generate, preview, and download datasets for your testing needs without entering a credit card or signing up for a paid plan.
Is the generated data GDPR and PII compliant? Yes. The data created by this tool is Synthetic Data. It mimics the structure and logic of real user data (e.g., valid email formats, matching cities/states) but is algorithmically generated. It does not correspond to any real individuals, making it safe to use in Staging and Dev environments while remaining fully compliant with GDPR, CCPA, and HIPAA regulations.
What file formats can I download? We support all major industry-standard formats to ensure compatibility with your stack. You can export your data as JSON, CSV, SQL, XML, or Excel (XLSX).
Can I generate specific data types like Credit Cards or IPs? Absolutely. Our library includes dozens of specific data categories, including Credit Card Numbers (Luhn validated), IPv4/IPv6 addresses, GUIDs, Dates, Phone Numbers, and Currency values.
Can I use this data for Load Testing? Yes. You can generate large volumes of rows to stress-test your databases or UI performance. Since the data structure is consistent, it serves as an excellent baseline for performance benchmarks.
How do I use this data with CloudQA automated tests? If you are using the CloudQA platform, you don’t even need to download the file. You can simply choose “Generate Data” inside your test step, and CloudQA will inject fresh, unique data into your forms every time the test runs.
Like the Data? You’ll Love the Automation.
You have the data, now automate the testing. CloudQA lets you use this data to drive codeless regression tests across your entire application.
