CSV with comma or semicolon?

In Windows it is dependent on the “Regional and Language Options” customize screen where you find a List separator. This is the char Windows applications expect to be the CSV separator.

Of course this only has effect in Windows applications, for example Excel will not automatically split data into columns if the file is not using the above mentioned separator. All applications that use Windows regional settings will have this behavior.

If you are writing a program for Windows that will require importing the CSV in other applications and you know that the list separator set for your target machines is ,, then go for it, otherwise I prefer ; since it causes less problems with decimal points, digit grouping and does not appear in much text.
