I wanted to count the number of non-blank items in a list of items using COUNTA. Cell A1 has the formula =COUNTA(A$2:A$10000, ISBLANK=0) above an otherwise empty column. It returns the value 1! Is that supposed to mean something?

Yes: it's the correct result!

The big question is what you intend the formula to mean. ISBLANK() is a function, so makes no sense without the parentheses and a parameter. Did you expect that second parameter to COUNTA() to mean something?

What were you actually trying to achieve? Do you want your formula to omit cells containing just blanks in its count, as well as empty cells? If so, you need to construct a formula that achieves this. But you need to speak Spreadsheet, not just English, to do so! Try

It's obviously not a big problem, because a workaround is obvious.

I don't think it's a problem at all.

But do I have to mistrust the results of the COUNTA function?

No. As others have said, if your specified range is empty, the first parameter contributes zero to the COUNTA() sum. But then the (apparently meaningless) second parameter contributes itself, so the total is indeed one.

I trust this helps.
