Fake contact list generator

Mock contacts and companies in the columns you choose as one CSV download.

Free for 10 runs a day.

A column list of First Name, Email and City beside fake contacts generated from it on .example email domains, with a Download CSV button.

Fake contacts in your columns

Real contact data cannot leave production. Typing fake rows by hand takes an afternoon. A copied sample never has the columns your import expects.

This tool builds fake contacts or companies in the columns you name and downloads them as a CSV.

Test the import before the real one

An import that fails halfway leaves half a list behind. A column lands in the wrong field. Nobody wants to learn that on customer contacts.

Dedupely merges the duplicates real imports leave behind and keeps each one in Merge History.

An import preview in a CRM sandbox: 500 fake contacts with every column in the file mapped to a CRM field and 0 errors.
