Hello,
(please understand that your question is not related to HikaShop or our support ; it's beyond the limit of what we can provide).
I would recommend you to add a column between the two prices and insert a unique content (a symbol you do not use, like # ).
Then export your content in CSV and thanks to a text editor, replace the separators and the # by your |
Regards,
