Test Data Generator

Build a realistic test table in your browser: pick the columns and their types, set the row count and a seed, then export CSV or Excel. Nothing is uploaded.

Columns

Column names become the header row of the exported file.

Fake but safe: emails use example.com/.net/.org and phone numbers use the 555 range — never a real person.

Set up the columns on the left, then generate a table.

How it works

  1. 1.Set up the columns on the left: name each one and pick its type — name, email, phone, company, city, date, price, UUID, fixed list and more.
  2. 2.Set the row count and a seed: the same seed always rebuilds the same table.
  3. 3.Choose the content style (English or Chinese names and cities) and press Generate data.
  4. 4.Export the table as CSV or Excel — emails stay on example.com and phone numbers in the 555 range, so nothing points at a real person.
