…? I must be misunderstanding you. I can't get ISO-8601 dates to work properly in Excel unless I set my Windows to Australia locale, or make my own parser or use a third-party library. Sure, I can format a field^Wcell with a custom format string, but Excel still won't believe me when I type/paste/import ISO-8601 dates. Unless I set 'Australia' systemwide. And no, simply adding English (Australia) as one of the additional system languages, or keyboard layouts (and switching to that layout), or number+date+currency formats doesn't work.
