About the dummy data (json/csv) generator

Realistic test data is essential for developing and demoing applications, but using real customer data risks privacy and compliance problems. A dummy data generator produces plausible-looking but entirely fake records you can safely paste into a database seed, a mockup, or a test suite.

Pick the fields you need (id, name, email, phone, address, company and more), choose how many rows to generate, and export the result as formatted JSON or CSV. Every value is generated locally with random names, domains and numbers — nothing is real and nothing leaves your browser.

Available fields

  • Identity — id, uuid, name, firstName, lastName, username.
  • Contact — email, phone, website.
  • Profile — age, city, address, company, jobTitle, salary, date, boolean.

Frequently asked questions

Is the generated data real?
No. Every name, email, phone number and address is randomly assembled from word lists and is entirely fictitious. None of the records correspond to real people.
What formats can I export?
Formatted JSON (an array of objects) or CSV (with a header row). Use JSON for APIs and databases, CSV for spreadsheets.
How many records can I generate?
Between 1 and 1,000 in a single batch. All generation happens in your browser, so very large batches may take a moment.
Can I choose which fields appear?
Yes. Toggle any of the 17 available fields on or off. Only selected fields are included in each record, in the order shown.
Is my generated data sent to a server?
No. All data is generated and formatted entirely in your browser.
