And that's not even the worst. You can teach people the few buttons necessary to read in the text, but once they save it again, the file is changed! Now you have a different separator and chances are good, excel also mangled date columns, removed leading zeros from numbers and switched out decimal separators! So you may not be able to further process the file. And its also sad, because if they just made some of these changes optional, excel would be a good tool to quickly work on an csv file and pass it on. But as is, I am always hesitant to work with csv in excel, because it mostly breaks and becomes unusable for further processing.
