Question 1

What is a fake JSON generator?

Accepted Answer

A fake JSON generator creates realistic but non-real JSON datasets based on a schema you define. It is useful for testing APIs, prototyping front-end interfaces, seeding databases, and creating demo data without touching real user information.

Question 2

What data types can I generate?

Accepted Answer

You can generate string, number, integer, boolean, email, full name, first name, last name, UUID, ISO date, URL, phone number, street address, company name, and lorem ipsum sentence. Each field type uses realistic random generation.

Question 3

How many records can I generate at once?

Accepted Answer

You can generate between 1 and 100 records per run. For larger datasets, click Generate multiple times and combine the outputs, or adjust the count and regenerate.

Question 4

Is the generated data safe to use for testing?

Accepted Answer

Yes. All data is generated locally in your browser using the Faker.js library. No real personal data is used and nothing is sent to any server. The data is entirely synthetic.

Question 5

Can I add custom field names?

Accepted Answer

Yes. Each field has an editable name input. You can rename fields to match your API schema exactly, for example 'userId', 'firstName', 'createdAt'. The generated JSON will use your custom field names.
