ARRAYFORMULA COUNTIF each row separately

Question

I try to COUNTIF(B2:Q2;\">5\") for each row and return the result for each row in column A but I clearly fail on using ARRAYFORMULA

Answer 1

In addition to Max's solution, I believe it should be possible to use COUNTIF(). See if this works

=ARRAYFORMULA(COUNTIF(IF(B2:Q>5,ROW(B2:B)), ROW(B2:B)))

Answer 2

Sample File

=ARRAYFORMULA(MMULT(FILTER(--(B2:Q>5),B2:B<>""),TRANSPOSE(COLUMN(B2:Q)^0)))

mmult is effective, but slow formula. I used filter to limit the number of calculations.

Edit. Here's another formula to do the same:

=ArrayFormula(LEN(SUBSTITUTE(SUBSTITUTE(TRANSPOSE(QUERY(TRANSPOSE(FILTER(--(B2:Q>5),B2:B<>"")),,100500)),"0", "")," ","")))

Looks clunky but should work faster (not tested).
