FAQ
Does the data look realistic?
Generated data uses preset pools of realistic names, email domains, and product names. All data is randomly combined and contains no real personal information.
Will generated data have duplicates?
ID fields use incremental indexing for uniqueness. Other fields (names, emails) are randomly selected from large data pools, making duplicates very unlikely within 1000 records.
