Fake Data Generator
LiveGenerate fake names, emails, addresses, phone numbers, and more in JSON, CSV, or SQL format.
Understanding Code & Data Generation
Realistic test data is essential for development, QA, and demos. Using production data in development environments creates privacy risks and compliance violations. Hardcoded fake data is tedious to maintain and looks obviously fake. A fake data generator produces realistic-looking names, addresses, emails, and other structured data at scale — perfect for database seeding, API testing, UI prototyping, and load testing without any real personal information.
Generate realistic fake test data including names, email addresses, phone numbers, company names, addresses, UUIDs, dates, and usernames. Configure the number of records and output format: JSON, CSV, or SQL INSERT statements. Perfect for database seeding, API testing, UI prototyping, and demo data. All generation happens in the browser — no API calls.
The Devkitr Fake Data Generator produces realistic test records with configurable fields including names, emails, phone numbers, addresses, companies, UUIDs, and dates. Choose the number of records and output format: JSON, CSV, or SQL INSERT statements.
In a typical development workflow, Fake Data Generator becomes valuable whenever you need to generate fake names, emails, addresses, phone numbers, and more in json, csv, or sql format. Whether you are working on a personal side project, maintaining production applications for a company, or collaborating with a distributed team across time zones, having a reliable browser-based generation tool eliminates the need to install desktop software, write one-off scripts, or send data to third-party services that may log or retain your information. Since Fake Data Generator processes everything locally on your device, your data stays private and your workflow stays uninterrupted — open a browser tab, paste your input, get your result.

How to Use Fake Data Generator
Select Fields
Check the data fields you want to include: name, email, phone, address, company, UUID, date, etc.
Set Record Count
Enter the number of fake records to generate (1–200).
Choose Format
Select output format: JSON array, CSV, or SQL INSERT statements.
Generate & Copy
Click Generate and copy the output for use in your seed scripts, test fixtures, or API mocks.
Use Cases
Database Seeding
Generate 100+ fake user records as SQL INSERT statements to seed development and staging databases with realistic-looking data.
API Testing
Generate fake user payloads as JSON to use in POST requests when testing user creation, search, and filtering endpoints.
UI Prototyping
Paste fake user data into prototype designs so stakeholders review layouts with realistic names and addresses instead of placeholder text.
Load Testing
Generate large datasets of fake records to feed into load testing scripts that simulate real traffic patterns against a live system.
Pro Tips
For SQL output, match the field names to your actual table column names before copying to avoid needing to rename columns in the INSERT statement.
Generate more records than you need and filter in your application — it is faster to copy from the generator than to re-generate with a different count.
Common Pitfalls
Using production data exports as test data
Fix: Even anonymized production data can contain PII. Use generated fake data in all non-production environments to eliminate privacy risk entirely.
