Dummy User Data Generator

What is Dummy Data?

Dummy Data (or mock data) is fake information used to populate databases, test software applications, or visualize UI designs. It allows developers to test how their systems handle "real-looking" data without compromising anyone's actual privacy.

Why You Need It

Performance Testing

Check how your application performs when loading lists of 100 or more users.

Table Layouts

Visualize data tables and grids with entries of varying lengths to ensure the UI doesn't break.

Demo Presentations

Show off your product to clients with professional-looking sample data instead of "Test User 1", "asdf", etc.

Professional Features

Multi-Format Export

Export your data in JSON for APIs, CSV for spreadsheets, SQL for databases, or XML for legacy systems.

Detail Control

Toggle specific fields like UUID, Avatar, Job Title, or IP Address to keep your data minimal or comprehensive.

Seeded Randomness

Need consistency? Enter a Seed value to generate the exact same "random" dataset every time you run tests.

SQL Generation

Skip the manual work. Generate ready-to-execute INSERT INTO users... SQL statements directly for your schema.

Mass Generation

Stress test your app by generating up to 1,000 user profiles in milliseconds with a single click.

100% Privacy

All processing happens in your browser. No data is sent to our servers, making it safe for internal project mocking.

How to use the Data Generator?

Frequently Asked Questions

What is a Dummy Data Generator?

A **Dummy Data Generator** is a tool that creates fake but realistic-looking data for testing software. It helps developers populate databases, test API endpoints, and visualize UI layouts without using sensitive real-user data.

What kind of data fields can I generate?

You can generate comprehensive user profiles including **UUID**, **Username**, **Password**, **First/Last Name**, **Email**, **Phone**, **Job Title**, **Company**, **Address**, **City**, **Zip Code**, and even **Avatar URLs**.

Can I generate SQL INSERT statements?

Yes! Select the **SQL** format to generate ready-to-execute `INSERT INTO` statements. You can even customize the table name to match your database schema.

How do I generate reproducible data?

Use the **Random Seed** feature. If you enter a seed (e.g., "test-v1"), the tool will generate the **exact same sequence** of users every time. This is perfect for consistent regression testing.

Can I download the generated data?

Yes, you can either **Copy** the result to your clipboard or click **Download** to save it as a `.json`, `.csv`, `.sql`, or `.xml` file directly to your device.

Is the generated data real?

No. All data is **randomly generated** using lists of common names, cities, and domains. Any resemblance to real persons or actual addresses is purely coincidental.

Is this tool free to use?

Yes, this tool is **100% free** and open for everyone. There are no limits on how many times you can use it, and no signup is required.

Does this tool work offline?

Yes! Once the page loads, all logic runs **locally in your browser** via JavaScript. You can generate data even without an active internet connection.

What formats are supported?

We currently support **JSON** (for APIs), **CSV** (for Excel/Sheets), **SQL** (for Databases), and **XML** (for legacy systems) formats.

Do you store generated data?

No. We prioritize your privacy. The data generation happens entirely on your device (Client-side), and **nothing is ever sent to our servers**.
