I have two Mac OS X machines, both running Microsoft EXCEL 2011.
One uses a comma to separate function parameters, e.g:
Yet my work machine uses semi-colons, e.g:
How and where can I change this?
The Excel 2011 function argument delimiter seems to be tied in to the region settings of OS X. I have been able to get a comma as argument delimiter in Excel by setting the region of the machine to the US or to the Netherlands. (It was originally Swiss-French)
This obviously also changes the usage of the komma and the dot in number notations and the convention for showing dates. These I was able to customize all back to my original preference via the customize buttons, whilst leaving the new argument delimiter behavior intact.
