Count number of values in a cell unless blank

Question

I have a cell that uses a drop-down list that allows for multiple selections. How do I count the number of selections?

I used this: =LEN(A2)-LEN(SUBSTITUTE(A2,\",\",\"\"

Answer 1

If your selections do not have spaces then substitute commas for spaces, trim the result then count for spaces as above with commas.

=LEN(trim(SUBSTITUTE(A2,","," ")))-LEN(SUBSTITUTE(trim(SUBSTITUTE(A2,","," "))," ",""))+sign(len(a2))
