Error when using SEQUENCE within COUNTIF

Error when using SEQUENCE within COUNTIF

Excel won't accept this formula, and I don't know why:

COUNTIF(SEQUENCE(20); "<9")

Wrapping it with like the following is accepted by Excel, but produces 20 rows of VALUE errors:

LET(
sequ; SEQUENCE(20);
COUNTIF(sequ; "<9")
)

All I want is the count of numbers in the sequence that are <9. Any ideas?

Re: Error when using SEQUENCE within COUNTIF

The short answer is COUNTIF (also, COUNTIFS, SUMIF, SUMIFS, AVERAGEIF, AVERAGEIFS, etc.) only accept ranges which have an address in the sheet (Sometimes referred to as 'target arrays'.  Functions like SEQUENCE generate arrays "in-memory").  It's the same reason why an array constant is not accepted either:

``=COUNTIF({1;2;3;4;5;6;7;8;9;10;11;12;13;14;15;16;17;18;19;20},">6"0``

You could create a spill by using =SEQUENCE(20) and then refer to the spill using # notation and COUNTIF will accept it because the values have an address in the sheet.

You might also arrange the formula as such:

``=COUNT(IF(SEQUENCE(20)>6,SEQUENCE(20)))``

Re: Error when using SEQUENCE within COUNTIF

COUNTIF() needs a reference and not an array.

This works:

Formula in A1

``=SEQUENCE(20)``

Formula in B1

``=COUNTIF(A1#,"<9")``

Or you could use mathematical logic:

``=9-1``

Re: Error when using SEQUENCE within COUNTIF

``=COUNT(IF(SEQUENCE(20)>6,SEQUENCE(20)))``

is a good workaround.

I found out that this one works just as well:

``=SUMPRODUCT(IF(SEQUENCE(20)>6, 1, 0))``

``=9-1``
``=9-1``
