Exporting All WooCommerce And Run It From Live CSV

I have a woocommerce store at the minute with around 700 products (including colour and size variations for some of them) – it is becoming rather time consuming trying to monitor these prices as my buy price changes all the time.

Is there a way I can export all the products (including images, variations etc) to a CSV, then add in new products / update prices in a CSV that I just drop in to my FTP folder that WooCommerce could sync so I can update the CSV with prices etc and just drop it in to FTP rather than updating the pricing manually in woocommerce each time prices are updated.

Hope someone can help with a tutorial / plugins on how to do this.
