Excuse my limited knowledge on CSV files, but is that not a text file?
No. They are different specialty formats, both recognized by MS Excel. The supported formats vary from website to website. So sometimes you need to modify your existing spreadsheet when bulk uploading. The bummer is, my spread sheet is missing the all important image URLs and I'm trying to see if I could U/L them then D/L then in a spreadsheet format. I am not going to do 400 lines of URL.
