Hi Stuff Worth Buying,
Thanks for posting your question here. Based on the error message you are receiving when attempted to upload this file into Auctiva, it sounds like you most likely selected the incorrect format when originally exporting the file from Turbo Lister.
Please ensure that you choose the “File Exchange Format (CSV)” option when you use the “Export Selected Items” option within Turbo Lister to create your file and I believe you will then be able to upload your items into Auctiva successfully.
If you continue to receive the same error after exporting your items in this format, please contact our Customer Support team directly from under the “Help” tab within your account and we will be happy to continue working with you on this.
