Export PXM Products in Commerce Manager
If you want to modify product attributes, export the products in Commerce Manager. This builds the .csv file containing the product entries. After the file is exported, you get a link to the location where the .csv file is stored. Then you can make changes to the product fields (modify product information, add main image files and custom extension data) using the product import function. For more information, see Import Products Overview
On the Products page, select the checkboxes next to the products that you want to modify. You may apply appropriate filters to select the products.
Click the arrow next to the checkbox on the header row and then click Export Products.
The Export Confirmation window appears.
