Hi SilverCJ,
The free listing tools provided at http://www.auctiva.com do not allow users the ability to upload listings from personal websites or from CSV files.
However, we do offer one listing product, Mister Poster, which allows users the capability to upload listings in CSV format. More information, along with a free 30-day trial of this product can be found at http://classic.auctiva.com.
