I think the Functions Translator[1][2] add-in might be worth a look to you. Note: I haven't used it myself, and it's a Microsoft Garage project, so there's no guarantee of support or maintenance.

From the description:

Functions Translator helps people use a localized version of Excel by helping translate from the US Excel function names, or research how to create a solution on the web with predominately English content.

Easily find the equivalent localized functions and formulas in any of the supported 15 languages. Functions Translator will automatically configure the language settings to US and the Localized version, and people can provide feedback on the translation of functions if it is not what they expected.
