Hello,

To import massive data in Odoo, follow these steps:

1. Go to the Inventory module.
2. Open the Product tab, then click on the gear icon next to "Products" in the top left corner.
3. Select Import Records.
4. I recommend downloading the Product Import Template available there. Fill it with your product data but avoid modifying the "External ID" column.
5. Once done, save the file as an Excel CSV (comma-delimited).
6. Finally, upload it back into Odoo. It's a good idea to test the file first before completing the upload.

Let me know if you need further help!
