I was able to export the custom filterable product attributes into individual columns in CSV file using BSSCommerce export extension. Now I have a large amount of data need to update.I have searched around the forum and found different answers. I would like to confirm the definite answer if Magento 2 (i'm using 2.2.6) default import allow us to import custom product attributes through csv with individual columns(using custom attribute names), or everything need to go under "additional_attributes" column?
For example: Can I import it like below:
SKU | custom-attr1 | custom-attr2 | custom-attr3 shirt | blue | xl | men
or does it has to be like:
SKU | additional_attributes shirt | custom-attr1=blue,custom-attr2=xl,custom-attr3=men
some related questions i found, but can't find the definitely answer for import.
