Product CSV Creation For Wordpress

I am looking for a competent product CSV creator for upload to my Wordpress site. I run an online furniture ecommerce website. We have 10 suppliers. Some of the suppliers do not give us a CSV sheet. So we have to scrape their websites. But most of the suppliers will give us a CSV and drop box full of images., We just need to manipulate the data to make it ready for import into wordpress. So I need someone who is 100% expert in this field. I also want to assign filters etc. to the products.
