Hi,

I need to manually change all product prices. Seems the only practical way is to export to spreadsheet then import again. Problem: everytime I do all products get duplicated

Is there a way to overwrite existing products with matching internal id?

Nevermind, I found out I must not select "export all" from the product's cog, but instead select the products I want to update, click Actions, Export, then tick "I want to update data".

Unfortunately I do not have the karma to close this request.
