使用列号的Excel公式范围参考

Question

I'm looking for a way to use the column number that I get from MATCH in a range reference. I need to count the number of X's in this row, up to a specific point. Here's some code as an example of what I'm trying to get to work.

=COUNTIF($A$14:MATCH($E$1| $A$13:$V$13)$14|"X")

I need to use MATCH (or something equivalent), as it lets me know the number of columns I need to count across. Users may or may not remember to clear out the whole row past this number of columns even though it should only count, say, 10 columns' worth of X's in this row. I already know exactly how many columns to count due to other data on the sheet (referenced as $E$1 in match) that matches a number in the check row, so something along these lines is a preferable solution.

Answer 1

You can use INDEX with MATCH to get the end of your range, eg

=COUNTIF($A$14:INDEX($14:$14,MATCH($E$1,$A$13:$V$13)),"X")

So if the MATCH function gives you 10, for example, that will count "x"s in A14:J14

Note that if you want an exact MATCH you need zero as third argument of MATCH function (I haven't included that)
