Here it is possible to import an export file from another web shop, among others standard with osCommerce. The only thing you have to do is to select the file (CSV, XML or osCommerce database file), and see if our web shop can recognise it. If you wish to transfer images you need to remember to tick off in “Transfer images” and enter the address of your current web shop.

If you have made a wrong import you can always empty your products. Learn more about this under Control panel > Shop settings.
