In Magento 2 default, admins can have all products attributes in your store exported in a CSV file. However, default Magento 2 does not support well with custom attributes. As these attributes will be shown in only one column “additional_attributes” separated by a comma, Custom Product Attribute Export for Magento 2 will solve this problem.
2. How Does It Work?
Please go to Stores ⇒ Configuration ⇒ BSSCOMMERCE ⇒ Product Export Column and start configuration.
In Enable: Choose Yes to enable the module or choose No to disable it.
In Allowed Attribute: Choose the custom product attributes which you want to be in separate columns when exporting products.
