Generate realistic fake data for testing and development. Export as JSON, CSV, or SQL.
The Mock Data Generator creates realistic fake data for software development, testing, and prototyping. It uses the industry-standard Faker.js library to generate believable names, email addresses, phone numbers, physical addresses, company names, and more.
Whether you're building a new API, populating a test database, creating UI mockups, or running load tests, this tool helps you generate the data you need quickly and privately. All generation happens in your browser, ensuring your test data workflows remain completely confidential.

What is mock data used for?
Mock data is used during software development and testing to simulate real data without using actual production data. It helps developers test their applications, populate databases, create API responses, and build realistic UI prototypes without privacy concerns or the need to access real user data.
Is the generated data realistic?
Yes! This tool uses the Faker.js library to generate realistic-looking data including proper name formats, valid email patterns, real city names, properly formatted phone numbers, and more. While the data looks authentic, it is all randomly generated and not associated with real people.
What output formats are available?
You can export your mock data in three formats: JSON (ideal for APIs and JavaScript applications), CSV (perfect for spreadsheets and data analysis), and SQL INSERT statements (ready to run against your database). Each format is properly formatted and ready to use.
Can I use this data in production?
While the generated data is technically safe to use, mock data is primarily intended for development and testing purposes. For production systems, you should use real data from your users (with proper consent) or carefully curated seed data that reflects your actual business requirements.
Is my data private?
Yes, absolutely. All data generation happens entirely in your browser. No data is sent to any server, and no information about your generated data is stored or collected. You can generate sensitive-looking test data with complete privacy.
