Create small JSON datasets with fictional names, example e-mails, UUID-like IDs, dates, and numbers.

UNDERSTAND THE TOOL

How to generate test data

What it creates

The generator produces simple structured records for UI states, mock APIs, demos, and development fixtures.

Choose fields

  • Select the columns you need.
  • Choose how many records to generate.
  • Copy the JSON output into your prototype or test fixture.

Safe fake data

Generated e-mails use a reserved example domain, and names are fictional combinations from a small local list.

Generated row example

Name, email, and number fields

A generated record can combine a fake name, an example.test email address, and a number from 0 to 999. The tool creates up to 100 rows at a time.

{ name: 'Ada Lovelace', email: 'ada.lovelace@example.test', number: 42 }

Fake data notes

Generated names, emails, dates, numbers, and UUIDs are for development samples only. Do not treat them as realistic demographic or production data.

Frequently Asked Questions

Can I generate real personal data?

No. The output is fake data for development and should not represent real people.

What format is exported?

The output is JSON, ready to copy.

How many rows can I generate?

This lightweight tool limits output to small batches so it stays fast in the browser.

Are the generated emails deliverable?

No. They use the reserved example.test domain, which is meant for examples and tests rather than real inboxes.
