I'd like to count all cells in a range where a given function evaluates to TRUE. The documentation for COUNTIF
& COUNTIFS
show text-matching and evaluation of =
,<>
,<
,>
, but nothing more sophisticated.
Here's an example with the function ISDATE
(could be any TRUE/FALSE function) as a sheet or as a table:
A | B | |
---|---|---|
1 | 7/28/2021 | <- is a date |
2 | 12/7/1941 | <- is a date |
3 | =TODAY() | <- is a date |
4 | foobar | <- is not a date |
5 | <- is not a date | |
6 | =COUNTIF(A1:A5, "=ISDATE()") | <- should evaluate to 3 |
Is something like that possible?
ISDATE
helper column. I'd like to understand what's possible within theCOUNTIF
condition specifically. (In the real spreadsheet in question, I don't have permissions to add a column.)
