Hi, I have some isuues exporting and reimporting the shopping cart to csv, when I export all the articles to csv, then I open the csv in excel, and then I put all the data into colums, then I modify prices, then I save the file in excel as csv, and I checked the file exported, with the new file created, and they are identical, so then I enter webiste x5 evo 12, and import the new file so the prices I modify get the change, but I get serevar errors, I recheked both files and they are identically with the formats webiste x5 is suposed to work, but nothing works, and I am talking about 5,000 products on the shopping cart, so this is very bad for updating the shoping cart, I need an advice for this issue
