We have an Excel sheet in which we collect some monthly data.
Each line contains a date and some value (in my boiled-down example here the date is always the first of each month and the values are [1..n]).
I am now trying to calculate an average of the values but not from ALL values but only those from the last quarter (i.e. where Date is >TODAY()-90).
TODAY() at the time of this writing is Jan. 30th, 2023, so I would expect the result to be 12, i.e. the average of the values for the last 3 months (11, 12, and 13).
A B
1 Date Value
2 01.01.2022 1
3 01.02.2022 2
4 01.03.2022 3
5 01.04.2022 4
6 01.05.2022 5
7 01.06.2022 6
8 01.07.2022 7
9 01.08.2022 8
10 01.09.2022 9
11 01.10.2022 10
12 01.11.2022 11
13 01.12.2022 12
14 01.01.2023 13
15
16 Avg. last 3 months:
17 #VALUE! <-- =AVERAGE(IF(A2:A14>(TODAY()-90);B2:B14;0))
18 #DIV/0! <-- =AVERAGEIF(A2:A14;">(TODAY()-90)";B2:B14)
I tried several approaches using AVERAGE(...) and AVERAGEIF(...) functions as shown above (and also several other variants) but I could not manage to get this working. All I ever get are error messages like #VALUE! or #DIV/0! :-(
Any idea how I can convince AVERAGE(IF) to only consider those values where the date is >today-90 days?
As per my comment:
=AVERAGEIF(A2:A14,">="&TODAY()-90,B2:B14)
Where the ampersand calculations operator is just a less-verbose way to concatenate different values. Here the 2nd parameter takes a string so using both parts on the left and right of the operator we create a value such as ">=12345".

Note, I have edited my original question to clarify my problem:
As the title suggests, I am looking for a way to combine the SUMPRODUCT functionalities with an INDEX and MATCH formula, but if a better approach exists to help solve the problem below I am also open to it.
In the below example, imagine that the tables are on different sheets. I have a report that has the sales of each ID in the rows and each month in the columns (first table). Unfortunately, the report only has IDs and not the region they belong to, but I do have a look up table which labels each ID with their respective region (second table):
A

My goal is to be able to aggregate the sales by region as per the result below. However I would only like to show sales data that belong to the month that is shown in cell D2.
Goal:

I have used the INDEX and MATCH combination to return a single value, but not sure how I can return multiple values with it and aggregate them at the same time. Any insight would be appreciated!
You may just use:
=SUMPRODUCT((Sheet1!B$1:D$1=D$1)*(Sheet1!H$2:H$8=A2),Sheet1!B2:D8)
Remember, SUMPRODUCT() could be quite heavy processing huge data, therefor to combine INDEX() and MATCH() is not a bad idea, but let's do it the other way around and nest the latter two into SUMPRODUCT() instead =):
=SUMPRODUCT(INDEX(Sheet1!B$2:D$8,0,MATCH(D$2,Sheet1!B$1:D$1,0))*(Sheet1!H$2:H$8=A2))
Another option using SUMIF+INDEX+MATCH function as in
In "Sheet2" B2, copied down :
=SUMIF(Sheet1!H:H,A2,INDEX(Sheet1!B$1:D$1,MATCH(D$2,Sheet1!B$1:D$1,0)))
I am working in excel and for some reason my sum or count function is not working properly. Or, perhaps I am not using the correct function or in the right way.

IF(SUM(A:A>0),28,"")
IF(SUM(E:E>0),31,"")
I have the above columns, I want the Max columns to show a specific number only if there is data in their respective month column. February has data, so it shows 28. March does not have any data so it shows no max. I need to look at the entire column or at least a large area (row 2 to row 2000).
The issue I am having is that if I do not have a value in the first row, but do have values in later rows, the sum or count function will to recognize that and will return zero.

IF(SUM(A:A>0),28,"")
I have tried both sum and count functions, neither are giving me the results I want. I have also tried making >= 1. I found from StackExchange that someone was having a similar problem and a solution was to change the cell format to a number. That did not work either. Any suggestions?
Per my comment, you could use COUNTA() which checks if a cell is blank.
While it doesn't answer the technical reason SUM/COUNT isn't working, it should work for your intended purposes.
=IF(COUNTA(A:A)>0,28,"")
I'm sorry if this has been answered. I've been searching around for awhile now.
I have a times series dataset that I need to perform calculations on based on the previous x time (last hour,day, etc).
My issues is that I don't know how to run these calculations since the time deltas are not standardized.
Example:
Column A - Time (in seconds lets say)
Column B - Value
Time Value Result(5)
01 3 0
02 5 3
04 4 8
07 8 9
09 6 12
13 4 6
14 4 10
15 1 8
22 9 0
33 7 0
How could I return the Result(5) column by summing the last 5 seconds from that one instance (row) (not including it)?
Thank you.
EDIT:
To clear up what I'm trying to do:
1) Find the previous 5 secs of data using column A and return that range of rows
2) Using that range of rows for the 5 previous secs, sum column B
3) Output in Column C (formula)
The following formula should do what you need (paste into C2 and drag down):
=SUMIFS($B$2:$B$11,$A$2:$A$11,">="&A2-5,$A$2:$A$11,"<"&A2)
Where YourTime is the time in the row you wish to look back and sum over.
I've tested and it works for the data you provided - expand the ranges as appropriate.
I have a requirement in which i have to pick up the initial value of each row in a crosstab..
My crosstab looks like this
value 1960 1970 2010 2011
aus 10 5 11 6
eng 5 2
bra 11 4
ind 8 11
i have to add another column which picks up the initial value for every row based on the year..
so the result should look like this.
value 1960 1970 2010 2011 initialValue
aus 10 5 11 6 10
eng 5 2 5
bra 11 4 11
ind 8 11 8
You should be able to use the minimum() function to determine the lowest value for year and then return the value corresponding to that. The expression for the initialValue data item would be something like:
total(
CASE
WHEN [Year] = minimum([Year] for [Language])
THEN [Value]
ELSE 0
END
for [Language])
We get the lowest year for the specific language in the data set using the minimum() function using the for clause to define the aggregation level. If the year of the row matches this number, we output the value, otherwise we output 0. We then total everything up for each language which should give us the value for the lowest year.
This solution assumes that the numbers displayed in your crosstab are totals of lower-level row detail. If the aggregate is something different, such as average or count, the wrapping summary function should be changed accordingly.
I have rows of data that contains numbers from 1 to 15, however these numbers can be in any sequence. For example here:
3 2 1 12 13 5 6 7 9 15 10 8 4 15 11
I know from a visual count these numbers above are all correct; as there are no duplicates, and all the numbers have values from 1 to 15. An example of a row of data I found to be wrong:
3 2 1 12 12 5 6 7 9 15 10 8 4 15
You can see this line has duplicated numbers i.e. 12, and number 11 is missing, so this row only has 14 elements in all.
However, I have many rows of data and it is impossible to visually check each row. I need to ensure in each row: there are 15 elements; there are no duplicates, and that the row contains values from 1 to 15 and find which rows are faulty to check these against the original paper data.
Is there a command or function that I can use in Excel to make this process easier?
You could find a set of conditions, each of which is true for rows that contain exactly those 15 numbers in any order and then test several of them. For example, if the row is in A5:O5:
=AND(COUNT(A5:O5)=15,SUM(A5:O5)=120,MIN(A5:O5)=1,MAX(A5:O5)=15,
AVERAGE(A5:O5)=8,ROUND(STDEV(A5:O5),3)=4.472)
This will show TRUE for a row that contains the integers 1 to 15 in any order, and is very unlikely (it could very well be impossible - I haven't checked) to show TRUE for a row that contains any different set of integers.
I'm pretty sure that the only way 15 positive integers less than 16 can add up to 120 other than by all being different is with duplication, so :
Check there are 15 numbers
Check their total is 120
Check the maximum is 15
Check not negative (nor zero):
=IF(OR(COUNT(A5:O5)<>15,SUM(A5:O5)<>120,MAX(A5:O5)>15,MIN(A5:O5)<1),"Error","Plausible")
then check for duplication with Conditional Formatting using a rule such as :
=COUNTIF($A5:$O5,A5)>1
and a distinctive format. Filter to select "Plausible" and then anything with a distnctive format is non compliant.
