Frequently Asked Questions

What is mock data used for? +

Mock data is used during development and testing when real data is unavailable. It lets you build and test UI components, populate databases for demos, test APIs with sample payloads, and create presentations without using sensitive production data.

What field types are available? +

Available types: firstName, lastName, fullName, email, phone, address, city, country, date, dateTime, number, float, boolean, UUID, username, URL, IP address, color, and lorem ipsum text.

How many records can I generate? +

You can generate 1 to 100 records at a time. Each record is a JSON object with the fields you defined.

Is the generated data realistic? +

Yes — names, emails, and phones follow realistic patterns. Names are drawn from a built-in dataset of common first and last names. Emails are generated using the first/last name if those fields exist in your schema.

Can I download the generated JSON? +

Yes — click Download JSON to save the output as a .json file. You can also click Copy to copy it to your clipboard for pasting into your project or API testing tool.
