The localisation of Excel goes even further. If I send a normal CSV file (that is, one containing values separated with actual commas and newlines) to an American, their Excel can open it. If I send the same file to a fellow Dutchman, their Excel can't. Excel, for some obscure reason lost in time, decreed that the Dutch do not, in fact, separate their comma-separated values with commas. We use semicolons. No one seems to know why Microsoft thinks we apparently do this. That means that a normal bog-standard CSV file won't work by just double-clicking it or opening it in Excel. That's right: a Dutch comma-separated values file must have semi-colons according to Excel. LibreOffice meanwhile works with anything you throw at it, in any language, of course. It'll just ask you about the separators, defaulting to commas.
