The two ones I have tried are Easy Populate and Excel Populate.

Easy Populate:

I have formatted everything just as the Wiki says and have confirmed the csv file IS comma-delimited. Hell, even though I am not using model #'s I even prefilled some ones I made up. I go to import and it gives me a different error!!!!

MySQLi error 1366: Incorrect integer value: '' for column 'products_discount_type' at row 1
When executing:
INSERT INTO products

Why does it say something about 'products_discount_type' when the Wiki mentions nothing about that column??!?!?

Excel Populate:

Attempt to import, gives no error, imports no products.

Any help is appreciated, because it's getting pretty aggravating!
