In a traditional export of product prices, an excel document will be generated that includes all products with pricing, omitting any products that have no pricing data. If you would like to export products with no pricing data saved, ostensibly to add pricing data, please follow the steps below.
Navigate to the Products tab
On the lefthand side, under Prices, select Export Prices
On the lefthand side select Export Products With No Prices (Format: Basic)
This will generate an excel file of ONLY those products without pricing data. You can then edit in excel, and upload back into Vinosmith.
