Hi,
In the HikaSerial backend, you can export the serials.
By selecting filters on a specific status and on a pack (if required) you can export all "used serials of pack X" ; if you do not select any serial in the list, it will export all serials corresponding to the current filters.
In the serial exports, you will have some details about the user.
HikaSerial is also integrated with the HikaShop order export, so you can have the serials data in the order export.
