Product of cells with changing row number - excel

I'd like to get the product of the last three cells in the certain column. The row numbers will change as the data increases. For example,
ColA
2
4
1
6
5
The product of the last three cells in ColA will be 30 (1*6*5).
ColA
2
4
1
6
5
7
3
Now the product of the last three cells in ColA becomes 105(5*7*3).
Is there a function in Excel (not =Product) that will do the calculation above?

Try this:
=PRODUCT(INDEX(A:A,MATCH(1E+99,A:A)-2):INDEX(A:A,MATCH(1E+99,A:A)))

I would like to SELECT 3 rows above and below WHERE Column B = someValue .
IF query SELECT * WHERE Column B = "Andrew" result should look like:
Column A
Column B
Column C

I know how to select one row, but cant understand how to select such range.
Thanks for ideas!
You can limit and offset inside your QUERY():
=QUERY(A1:C,"limit "&2+MIN(5,MATCH(D1,B:B,0))&" offset "&MAX(0,MATCH(D1,B:B,0)-5))
Well, this was fun...
If 3 above or below are not available then blank... rolling data around is a different proposition.
Below the image is the list of formulae used.
So, per cell not including the data validation that is based on cells B2:B11
A14 and dragged down:
=IFERROR(INDEX($A$2:$A$11,MATCH(B14,$B$2:$B$11,0)),"")
C14 and dragged down:
=IFERROR(INDEX($C$2:$C$11,MATCH(B14,$B$2:$B$11,0)),"")
Cells B14 through B20:
=IFERROR(IF(MATCH(B$17,$B$2:$B$11,0)=3,NA(),INDEX($B$2:$B$11,MATCH(B$17,$B$2:$B$11,0)-3)),"")
=IFERROR(IF(MATCH(B$17,$B$2:$B$11,0)=2,NA(),INDEX($B$2:$B$11,MATCH(B$17,$B$2:$B$11,0)-2)),"")
=IFERROR(IF(MATCH(B$17,$B$2:$B$11,0)=1,NA(),INDEX($B$2:$B$11,MATCH(B$17,$B$2:$B$11,0)-1)),"")
=E2
=IFERROR(INDEX($B$2:$B$11,MATCH(B$17,$B$2:$B$11,0)+1),"")
=IFERROR(INDEX($B$2:$B$11,MATCH(B$17,$B$2:$B$11,0)+2),"")
=IFERROR(INDEX($B$2:$B$11,MATCH(B$17,$B$2:$B$11,0)+3),"")
In Excel 365, you could try:
=INDEX(A:C,MAX(2,MATCH(D2,B:B,0)-3),0):INDEX(A:C,MIN(COUNTA(B:B),MATCH(D2,B:B,0)+3),0)
In Google sheets, on the other hand, the formula would be:
=INDEX(A:C,MAX(2,MATCH(D2,B:B,0)-3),0):INDEX(A:C,MIN(COUNTA(B:B),MATCH(D2,B:B,0)+3),0)
(spot the difference).
Excel
Google Sheets
This should produce what you want in all cases:
=IFERROR(FILTER(A2:C,B2:B<>"",ROW(A2:A)>=VLOOKUP("Andrew",{B2:B,ROW(B2:B)},2,FALSE)-3,ROW(A2:A)<=VLOOKUP("Andrew",{B2:B,ROW(B2:B)},2,FALSE)+3))
Of course, you can replace the two instances of "Andrew" with a cell reference (one where you type a changeable name).
This just looks up the row in a curly-bracket array formed from the names and row numbers and uses FILTER to keep results to rows between +/-3 rows of where the target name is found. If you choose the first name (or any other name), you won't get an error; because even if the target name were on Row 1 and the formula goes looking for anything "greater than or equal to 1 minus 3, all rows will be greater than a negative number. Same on the high end. You just won't get a full seven names if there aren't at least three other rows prior to or after the target row.
this not the best solution but it will work , you can use a helper column 'D' that contains the following formula =if(countif(INDIRECT("B"&ROW()+3&":"&"B"&ROW()-3),"Andrew")>0,TRUE,FASLE)
and u can query from here like this SELECT * WHERE Column D = TRUE

Dynamically change row number in excel

I got a file in excel that often changes the row number (My first column) whenever there is a insertion of data. However, there is multiple rows of data with the same row number.
Example:
1
1
2
3
3
3
Is there a way I can change them dynamically beside grouping the number together via Filter and change it manually?
Edited.

Better example. Sorry about the indentation.
I can propose a partial solution.
Set the value only in the first identical value and change only those unique values when a group of rows is inserted:
1 1
1 =A1
1 =A2
2 2
3 3
4 4
4 =A6
4 =A7
Otherwise, you do it from VBA to change all values when a new row is inserted.

Sum across columns based on 3 criteria

I'm trying to get a Sumif working across multiple rows.
For example, say my data source is below:
A B C
1 1 10 11
2 2 9 12
3 3 8 13
4 4 7 14
5 5 6 58
I want to sum from Columns A to C, in row 3. Output would be 24.
Ideally my criteria for the Horizontal Start, Horizontal End and Vertical would all be referenced in different cells which can be updated to get a new result depending on the criteria.
Is this possible so that the criteria cells can be updated and the formula will update accordingly?
Use a SUMIF, and betweem the logical criteria, simply use 3 criterias by seperating each with "&"'. This says that excel will sum if a happens, and b and c.

Summing a set of values based on cell content and row position

In the below table rows 2,3 and 4 have some details of a sporting event.
Range A2:C4 has a set of squad numbers and range D2:F4 has the details of who scored goals.
A B C D E F
1 Squad # Scorers
2 1 3 6 2 8 3
3 3 6 7 6 1
4 1 5 6 7 2 4
As an example squad # 6 has scored 8 goals based on the values equivalent position in the Squad section and relative to the Scorers range.
What formula will give me this total value and the equivalent total values for all squad numbers like the table below?
Some cells will be empty like F3.
1 9
3 14
5 2
6 8
7 0
A simple SUMPRODUCT function should take care of this.
=SUMPRODUCT($D$2:$F$4, --($A$2:$C$4=H2))
Fill down as necessary.
        
With only 3 games, the simplest way that I can see to do this would be to use 4 SUMIFS statements, as follows [assumes that your results data is in columns A & B, starting at row 5 and moving down; A5:A12 would hold the IDs for the different squads, and this formula would go in B5 and be copied down]:
=SUMIFS($D$2:$F$2,$A$2:$C$2,A5)+SUMIFS($D$3:$F$3,$A$3:$C$3,A5)+SUMIFS($D$4:$F$4,$A$4:$C$4,A5)
What it does is sum columns D:F, for row 1, row 2, and row 3, based on the fact that columns A:C for those rows match the appropriate squad ID.
This would be possible with an arguably shorter but more complex Array Formula, but with the data as you've presented it, I feel this is the clearest method.

Return list of matching rows

Sheet1
A B C D
1 2 3 4
2 4 5 6
3 3 5 6
4 7 3 1
5 4 6 7
Sheet 2
A B C D
1 4
2 1
3 1 3 4
4 1 2 5
5 2 3
6 2 3 5
7 4 5
Column A of Sheet 2 has a non repeating listing of all values in Sheet 1. I would like a forumla so Col B of Sheet 2 lists the value of Sheet 1 Col A for each row where the Sheet 2 Col A lookup value is found. Either giving me a comma sep list or putting the results in sheet 2 Col B,C,D,...
I came up with a solution, but it involves a handful of formulas, not just one. Hopefully, you will still find it useful.
Your Sheet2 would basically look like this:
Here are the formulas you need to enter:
B1: =IFERROR(SMALL($G4:$U4,COLUMN()-1),"") [drag down and across to D7]
G1: =IF(F2=$W2,F1+1,MAX(1,F1)) [drag across to U1]
G2: =IF(F2=$W2,1,F2+1) [drag across to U2]
G3: =INDEX(Sheet1!B$1:D$5,G1,G2) [drag across to U3]
G4: =IF(G$3=$F4,G$1,"") [drag down and across to U10]
What this does is organize the Sheet1 data into rows, where each row corresponds to a lookup value. Then, it grabs the smallest value, the second smallest value (if one exists), and third smallest value (if one exists) from each row.
This should be easy to scale to as large a spreadsheet as you need (as long as you don't run out of columns).
