in the Office Template for Excel and the new FILTER function, there are some issues in the first example on the sheet Beispiel 1. Please do not care of #NAME? in the screenshot below, as I opened the file in an Excel Version, which does not have the FILTER-Function yet.
The content of the blue boxes in that image is untranslated. In a German Excel-Version, the default argument separator is a semi-colon and not a comma.
The explanation on the top mentions verschüttete Array-Formel, what for me sounds not good in German in this context, I think. The English version talks about a spilled array formula - so the term spilled is the issue. Maybe dynamische Array-Formel would be a better wording.
