"COUNTIF" non-empty cells

Hello,

I am using the latest version of Excel for Mac.

I am looking for a formula that allows me to count non-empty cells but, if all are empty, returns a blank cell instead of 0.

Let me explain:

- There are 5 cells in a row.
- 3 of these cells are filled
- When entering the formula countif(a1:a5,"<>") I will get the result in a6: 3

If now all the cells are empty, in a6 I will get: 0

What I want is that in this case, I have a blank cell.

Thank you
