Fake Data Generator

What is fake data generator?

Developers and designers often need sample data to test a form, fill a table or demo an app. Real customer data should never be used for that, so made up data is the safe choice.

This generator mixes common first and last names with safe email, phone and address patterns, and exports them as JSON or CSV.

How to use the fake data generator

1. Set how many records you need.
2. Tick the fields to include.
3. Choose JSON or CSV and copy the result.

How the fake data generator works

Each record picks random names, a company and an address from built in lists. Emails use the reserved example.com domain and phone numbers use the 555 range, which are not assigned to real people.

Worked example

Common uses of the fake data generator

• Filling a demo database.
• Testing a signup form.
• Designing tables and dashboards.
• Preparing screenshots without real customers.
• Teaching spreadsheets and SQL.

Tips and common mistakes

Do not use this data for fraud, spam or identity purposes.

For larger or localized datasets, write a script around the same idea.

Background: what to know before you rely on it

Using production data in testing is a privacy and compliance risk. Copies of real customer records leak through screenshots, logs and shared files. Synthetic data avoids that. Good test data covers more than the happy path: long names, apostrophes, accents and empty values reveal bugs that simple samples miss. This tool gives a clean baseline, and you can edit the output by hand to add awkward cases. Reserved domains and number ranges exist so that sample values cannot reach real people.
