Options

Rows

Seed

The same seed gives the same data. Change it for a new set.

Names and places

Write the columns you want, one per line. Use label:type to name a column, for example home:city. Names, emails, cities and PIN codes in the same row match each other, so the data looks real. Nothing here belongs to a real person.

Use the same seed to get identical data again.
SQL output is an INSERT statement ready to paste into your test database.
Never use these IDs where a real one is required; they are made to be invalid.

Rows come from a seeded pseudo-random generator (mulberry32) over small built-in word lists. Fake IDs are generated, then checked against the Verhoeff (Aadhaar) and Luhn (cards) algorithms and the PAN format, and redrawn until they fail. Runs entirely in your browser.

What are the limits of Mock Data Generator?

All data is invented. Emails use reserved example domains and phone numbers cannot be dialled. Fake Aadhaar, PAN, card, GSTIN and IFSC values are built to fail their checks, so they will not pass a real validator. Up to 1,000 rows and 30 columns. Your data stays on your device.
