How do I change language in Excel 2011 for Mac?
I'm not asking about the dictionary, I'm asking about the language of the program itself, i.e. the one of the menus.
(in case this matters, I'm using the trial of Office 365)
You have to install the localized version. It doesn't look like LIPs support OS X: http://office.microsoft.com/en-us/downloads/office-language-interface-pack-lip-downloads-HA001113350.aspx
