Fake Data Generator
Build realistic mock datasets — names, emails, addresses, dates, UUIDs and more — then export JSON, CSV or SQL. Everything is generated in your browser.
This fake data generator builds realistic mock datasets from a schema you design, then exports them. Use it to create test data, seed a database, or make sample rows of names, emails, addresses, dates and UUIDs for a demo. Set the row count and a seed so the same data can be reproduced, then export JSON, CSV or a SQL INSERT script. Everything is generated in your browser.

How it works
- 1
Design the schema
Add a field for each column, name it, and pick a type from the list — names, emails, numbers, dates and dozens more.
- 2
Set the row count
Choose how many rows you need, then generate. Reseed for a fresh batch or keep the seed for repeatable data.
- 3
Export
Copy or download the result as JSON, CSV or a SQL INSERT script, ready to drop into a database or test fixture.
Instant & 100% private — nothing is uploaded
Everything runs locally in your browser. Your code, text and files are processed on your own device and are never sent to a server — so there are no upload waits, no size limits from us, and nothing is ever stored or logged.
Frequently asked questions
- What data types can it generate?
- Common fields for app and database testing: full/first/last names, email, username, phone, street address, city, country, company, job title, paragraph and sentence text, numbers, decimals, booleans, dates, UUIDs, colors, URLs and more.
- Can I get the same data again?
- Yes. The generator is seeded, so the same seed and schema reproduce the same rows. Change the seed (or hit reseed) for a different set — useful for stable test fixtures.
- Which export formats are supported?
- JSON (array of objects), CSV (with a header row) and a SQL INSERT script for a table name you choose. All three are generated locally and copy or download instantly.
