Count a value in a range which depends on start and end date
=SUMPRODUCT(($E$1:$AI$1>=$AM$1)*($E$1:$AI$1<=$AO$1)*($E$2:$AI$7="A")*($D$2:$D$7=AN7))
SUMPRODUCT returns the expected result in my sheet.
Dear OliverScheurich,
Hi again, I hope you are doing very well...
U helped me a lot on the same issue, but I have one requirement in the same subject
If I need to list all the absent days for all students like in table AK21:AM33 between 2 periods same as before,
how can I do it for each student who has absent days...
More than appreciated ...
Hello Eyad_Kurdi,
you are welcome. I hope you are doing very well too.
=LET(z,DROP(REDUCE("",C3:C8,LAMBDA(u,v,
VSTACK(u,
LET(student_range,FILTER(E3:AI8,C3:C8=v),
absent_days_range,FILTER(E1:AI1,student_range="A"),
absent_days_range_filtered,FILTER(absent_days_range,(absent_days_range>=AM1)*(absent_days_range<=AO1)),
count_absent_days,COUNT(absent_days_range_filtered),
IF(count_absent_days=0,{"".""},
HSTACK(
IFNA(EXPAND(v,count_absent_days),v),
TRANSPOSE(absent_days_range_filtered))))))),1),
LET(count_all,COUNT(TAKE(z,,-1)),
VSTACK(
{"ID"."Name"."Days"},
HSTACK(SEQUENCE(count_all),FILTER(z,LEN(TAKE(z,,1))>0)))))
This formula works in my sample sheet. However it only works with Office 365 and Excel for the web. Functions such as LAMBDA and REDUCE aren't available in older versions of Excel.
- Dear OliverScheurich,
Finding the right words to convey my deep appreciation for everything you do is quite challenging. Dear OliverScheurich
I have a new approach that there are two types of attendance A and PIf I wanna list all days for both types and add a new column refer to the absent type like in the attached file AN21:AN28
and modify the old formula in cell AK21 to accept both A AND P
I wonder if you will help me this time ,,,, so embarrassed of your kindness 🙂
Hello, attached is my suggestion for this scenario. Kind regards.
