I\'m a bit confused here.
When I use Excel 2003 to export a sheet to CSV, it actually uses semicolons ...
Col1;Col2;Col3 shfdh;dfhdsfhd;fdhsdfh dgsgs
Check what delimiter is specified on your computer. Control Panel > Regional and Language Options > Regional Options tab - click Customize button. There's an option there called "List separator". I suspect this is set to semi-colon.
