I am ranking answer for a form. and I came up with this formula
=ArrayFormula(QUERY({'LEADs oGV'!U:U,LEN('LEADs oGV'!U:U)},
"select Col1, count(Col2) where Col2 > 0 group by Col1 order by count(Col2) desc limit 3",
0))
The problem is that it does not count the number of blank answers in the given column! How can I do that without filling every single blank cell?
