Fake Data Generator

The Fake Data Generator creates realistic-looking test data for software development, QA testing, database seeding, and demo environments. All data is generated entirely in your browser using JavaScript -- nothing is sent to a server and no personal data is collected.

Common Use Cases

• Database seeding -- Populate development and staging databases with realistic test records.
• API testing -- Generate payloads in JSON or XML for testing REST and GraphQL endpoints.
• UI prototyping -- Fill tables, forms, and dashboards with sample data to evaluate layouts.
• Load testing -- Generate hundreds or thousands of records to stress-test your application.
• Demo data -- Create professional-looking datasets for presentations and client demos.
• CSV imports -- Download CSV files ready to import into spreadsheets or CRM tools.

Supported Data Types

Choose from 17 data types including names, emails, phone numbers, physical addresses, company names, job titles, dates of birth, UUIDs, IP addresses, test credit card numbers, URLs, usernames, passwords, hex colors, and geographic coordinates. Each field uses curated data arrays with 50 to 120+ entries for natural-looking variety.

Output Formats

Export your generated data in four popular formats: JSON for APIs and JavaScript applications, CSV for spreadsheets and data imports, SQL INSERT statements ready to run against MySQL or PostgreSQL, and XML for enterprise integrations and SOAP services.

Privacy & Safety

All data generation happens locally in your browser. No data is transmitted to any server. The credit card numbers use well-known test prefixes (like 4111...) and are not valid for real transactions. Generated names and addresses are random combinations that do not correspond to real individuals.
