Google Sheet: COUNTA not recognizing blank cell generated by formula

Question

Live Sheet: https://docs.google.com/spreadsheets/d/1KcZiQLad_LDQ41rxRZsayY3jUQ7a35k1vFv3Y0tuSEk/edit?usp=sharing

I use COUNTA to calculate non-blank cells in a column. But if a blank cell is generated by a formula, COUNTA will regard it as a non-blank cell. From the sheet above you can see even if I import the formula generated blank cell to another cell ( so when you click on the cell the formula won't show and it looks like a genuine blank cell ), COUNTA will still see it as a non-blank cell.

Is there anyway to workaround this?

Answer 1

or you can do:

=IF(C1, 1, IF(,,))

Answer 2

Remove "":

=IF(C1,1,)
