maybe this is already in your database, as the following problem is also present in Excel 2010 and I guess Excel 2013 too. When calling the functions assistant for the function SVERWEIS (VLOOKUP in English) in Excel 2016 German, a help text is displayed when clicking in the arguments fields. For the last argument, the German translation is too long. Below some screenshots.
I suggest to shorten the text for the German translation. Currently it is not so much useful, I think.
