Custom Schema
Name your own columns and pick from over twenty field types, so the data matches your real table.
Generate realistic fake test data, names, emails, addresses, dates, and more, then export it as JSON, CSV, or SQL. Build your own fields and row count. Free, no signup, runs in your browser.
Name each column and pick a type, like full name, email, or date. Add or remove fields to match your schema.

Click Generate, then copy the output or download the file straight to your project.
Building a feature is hard to judge against three rows of placeholder text. Real looking data, a list of users with names, emails, cities, and signup dates, shows how your table, list, or export actually behaves once it fills up. A mock data generator gives you that in seconds, without writing a seed script by hand.
This tool lets you define the exact schema you need. Name each column and choose a type from over twenty options, including full names, emails, phone numbers, street addresses, companies, job titles, dates, booleans, numbers, UUIDs, and more. Set the row count, then export as a JSON array for an API mock, a CSV for a spreadsheet import, or SQL insert statements to seed a database directly.
It is handy for testing tables and pagination, building demos, loading staging databases, and trying out a chart with realistic numbers. Everything is generated in your browser, so nothing is sent anywhere and you can run it as many times as you like.
