How to use the Fake Data Generator
- 1. List your columnsOne per line as name: type, for example email: email.
- 2. Set rows and seedUp to 1,000 rows. The same seed always gives the same data.
- 3. DownloadChoose JSON, CSV or SQL INSERT and save the file.
Column types
22 types are available: id, uuid, first, last, name, email, phone, age, dob, date, city, state, pin, address, company, job, course, salary, price, rating, bool and status. City, state and PIN code in the same row always match each other, so a row with Pune has Maharashtra and 411001.
The data is made up. Names are picked from fixed lists, emails use example.com (a domain reserved for documentation), and phone numbers are random. That makes the data safe to put in demos, screenshots, test databases and bug reports, unlike copying real customer data, which can break privacy rules.
Worked example
The default 7 columns with seed 42 and 10 rows start with:
{
"id": 1,
"name": "Aarav Das",
"email": "aarav.das97@example.com",
"phone": "+91 63844 11145",
"city": "Chandigarh",
"course": "Software Testing",
"joined": "2025-01-22"
}Run it again with seed 42 and you get exactly the same rows, so automated tests and teammates see identical data. Change the seed for a fresh set.
- JSON: for mocking APIs or seeding MongoDB.
- CSV: for Excel, Power BI or pandas practice.
- SQL INSERT: one statement for a table called people. Rename it to match your table.
Tip: add a few messy rows by hand (blank emails, duplicate names) when you want to practise data cleaning.
Frequently asked questions
Are these real people?
No. Every value is generated from lists in your browser. Any match with a real person is a coincidence.
Can I get more than 1,000 rows?
Generate several files with different seeds and combine them.
Will the phone numbers work?
They are random 10-digit numbers starting with 6–9. Never use them to call or message anyone.
Is the fake data generator free?
Yes, it is free. Generating your first data set asks for your name and WhatsApp number once. After that, the fake data generator and every other Uncodemy tool open with no form.
