Question 1

What is mock data and why generate it?

Accepted Answer

Mock (or dummy) data is realistic-looking fake data used to populate databases, test APIs, build UI prototypes, and run load tests without exposing real personal information.

Question 2

Which output formats are supported?

Accepted Answer

You can export the generated rows as JSON, CSV, or SQL INSERT statements with a custom table name.

Question 3

Is the data sent to a server?

Accepted Answer

No. All data is generated locally in your browser with JavaScript. Nothing is uploaded, so it is safe for sensitive projects.

Question 4

Can I reproduce the same data again?

Accepted Answer

Yes. Enter a seed value and the random generator produces the exact same dataset every time, which is useful for repeatable tests.

Question 5

Does it support Japanese names and addresses?

Accepted Answer

Yes. Switch the locale to Japanese (ja) and names, addresses, phone numbers, and companies follow Japanese conventions.
