i need to be able to upload excel databse to oscommerce

hello guys right i need to be able to upload an excel database file in to oscommerce and it will add the products for me, the reason is that my supplier will send me up to date prices and products in exel ok so i will need it set to accept the upload straight from the suppliers one with out me having to change anything. the headings are like cat - product id - picture url - price - description - and so on..... sumthing like that they already come to me filled in also with the picture url as listed for each product in database i will be using the same description and picture as they do. i hope you understand this. thank you. on oscommerce i think they have a contrib for this but it may need to be altered to match the same columns headings as in my suppliers excel database
