Importation fichier csv

This sounds frustrating, Philippe! I’ve run into similar issues before with WooCommerce imports. Double-check that your CSV column headers exactly match the expected fields in WooCommerce (SKU, name, description, etc.). Even a slight difference in capitalization or a missing required field can cause the import to fail. Also, examine the product type; some require a specific column. Do you know the slope of the learning curve others had importing this certain product? If not, consider trying a very small sample import (just one or two products) with minimal data to see if that works, then gradually add more fields.
