I have repeatedly seen people getting the spreadsheets altered by excel, and in general a lot of troubles due to localisation reasons. Sometimes these changes can be subtle and be hard to spot until somebody tries to troubleshoot what went wrong down the line. It works better if you click to "import the data" instead of just opening the csv file with it, and if you then choose the right data types. But having to do this everytime to make it work is really annoying, esp when you have a lot of columns, plus people can easily get confused with the data types. I have never seen that much confusion eg with macos's numbers.
