bulk post uploading from excel for wordpress auctions

I would like to have a very easy to use excel template where i can fill in the fields that of the wp auctions wordpress plugin (view my auctions at [login to view URL]) excel, bulk upload all of the listings and have the posts be filled out. Each auction then needs its own post and it is inserted with a shortcode. I would love to have something that can automatically put the auction ID shortcode into its own post after the auction is created so that I dont have to do an extra step. i started to make my own template with the following column titles which would be sufficient..i would also like a place to specify which category the POSTs would be in (not the auctions bc the shortcode to the auctions go into a post which needs to be categorized). wp_title wp_description wp_Image_URL wp_start_price wp_end_date wp_shipping_price wp_shipping_to wp_shipping-form wp_Buy_it_now wp_extra_image_url_1 wp_extra_image_url_2 wp_extra_image_url_3 wp_tags
