this post addresses another question in the preceding thread ...

I ran into an additional problem.

I need to filter out any number above 3999 that gets retrieved from the other sheets. I can't wrap my head around how do it with such a complex formula.

=ArrayFormula(sort(unique(TRANSPOSE(SPLIT(CONCATENATE(Jan!A2:A&CHAR(9);Feb!A2:A&CHAR(9);Mar!A2:A&CHAR(9);Apr!A2:A&CHAR(9);Mai!A2:A&CHAR(9);Jun!A2:A&CHAR(9);Jul!A2:A&CHAR(9);Aug!A2:A&CHAR(9);Sep!A2:A&CHAR(9);Okt!A2:A&CHAR(9);Nov!A2:A&CHAR(9);Des!A2:A&CHAR(9));CHAR(9))))))
