What Is a Dummy Data Generator?

A dummy data generator is a tool that automatically creates realistic fake data so you can test applications, databases, APIs, and software workflows without using real personal data.

Our dummy data generator helps you create structured data for any project, with options for field types, formats, volume, and export formats.

Core features

  • ✔ 20+ field types like names, emails, addresses, phones, dates, numbers, companies & more
  • ✔ Multiple export formats: JSON, CSV, Excel, MySQL, PHP, TypeScript
  • ✔ Unlimited rows — generate any amount of data
  • ✔ Drag-and-drop field builder

It naturally fits searches like:
sql server dummy data generator, dummy excel data generator, json dummy data generator, dummy data generator online, create dummy json data online, dummy csv file generator, mysql dummy data generator, and more.

Why Choose Our Dummy Data Generator?

There are dozens of fake data tools online—but here’s why ours stands out:

1. Extremely easy for beginners

No coding required. Just add fields, choose a type, reorder them, and generate.

2. Saves hours of manual work

Instead of writing loops, validating fields, fixing formatting, or searching random datasets, you generate everything in seconds.

Example:
A startup building a new dashboard needs 5,000+ rows of realistic customer data. Instead of manually collecting or buying datasets, they generate it instantly—with correct formats and structure.

5. Supports developer-friendly formats

JSON for APIs, TypeScript for frontend apps, CSV for spreadsheets, MySQL for databases, and Excel for corporate reporting.

6. Works for anything

  • Web apps
  • SQL databases
  • Automation testing
  • API mocks

Real-World Use Cases and Examples

1. Web and Mobile App Development

Developers need sample data to build UI components, dashboards, listings, feeds, and forms. Instead of manually typing data, they generate real-looking records instantly.

2. Database Testing (SQL, MySQL, MariaDB)

If you're testing how databases handle large datasets, generating thousands of rows helps measure performance and indexing.

3. API Development & Mocking

You can create JSON datasets to simulate API responses and build full interfaces before the backend is ready.
