If I am trying to import an Excel file to update the product and services list, is It will Denied? Cause of changing the sale price and cost of goods for existing items?

I am trying to import an Excel file to update the product and services list. Specifically, I am attempting to change the sale price and cost of goods for existing items. However, the system is denying the import, stating that the product names are the same. Even after attempting to import without changing the product names, the import is still denied with a message to "change the info in the highlighted fields and try again". Could you please provide some guidance on how to resolve this issue?.
