Do you have multiple products with the same SKU?
In rare cases where data migration or third party apps have somehow created duplicate SKUs, you will need to replace the sku column with the entity_id column from your export in order for the system to properly map the data.
Once your file is ready go to Import & Export > Import Products.
- Set Entity Type to Products
- Set Import Behavior to SKU Replacement
Special characters (except "Dash -" and "Underscore _" and spaces) are not allowed for SKUs.
