Fake JSON Data Generator

The Fake JSON Data Generator creates realistic mock datasets from a schema you define. Add fields, pick a data type for each — names, emails, phone numbers, dates, UUIDs, prices and more — choose how many records you need, and generate a JSON array you can copy or download. Everything runs in your browser.

What is a Fake JSON Data Generator?

A fake JSON data generator produces realistic-looking but entirely random sample data in JSON format. Developers use it to seed databases, populate UI mockups, and provide stand-in responses for APIs that aren't built yet — without exposing any real user data.

This generator lets you define exactly the fields you need and the type of data for each, then produces a clean JSON array of as many records as you want. Because it runs entirely in your browser, nothing is uploaded and generation is instant.

How to use it

  • Add fields and give each a name and a data type
  • Choose data types like full name, email, date, UUID, boolean or price
  • Set how many records to generate (up to 1000)
  • Click Generate, then copy the JSON or download it as a .json file

Supported data types

  • Identity: full/first/last name, username, email, phone, avatar
  • Values: number, age, boolean, price, color, date, UUID
  • Content: city, country, company, job title, lorem sentence, URL
