Can I generate real personal data?

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.

How to generate test data

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

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 locally

The dataset is generated in your browser and is not saved by ProntoUso.
