An online store engine with a simple filling/updating of products?

Question

CMS

I am looking for cms for an online store (showcase), with a simple import and update of goods and prices.
Import from excel or csv, one or two files (products / descriptions for them), preferably a solution in php. Or recommend a product import module for drupal with similar characteristics.

Answer 1

Import from excel or csv, one or two files (products / descriptions for them)

What is the structure and order of the fields?
