Hi ,
for the moment there is no way to export the base weight of a product in WPC.
But there is a workaround you can use only if you are not currently using in your logic the base price.
You can set the base price of a product to the value of the its weight, and use it in your excel file , because it can me mapped in our software.
Otherwise if this solution don’t suits your needs, you can ask for a quote about this future sending an email to : https://altoswebsolutions.com/contact-us.
Best regards.
