Question

A challenge for the excel users:
I have a table with the following columns:

Year || Week || Output
2011 ||  50  || 1000
2011 ||  51  || 2000
2011 ||  52  || 1500
2012 ||  01  || 1200
2012 ||  02  || 1700
2012 ||  03  || 1900

I want to sum the values on the column output that are between a given year/week and another year/week. Example:

• between 2011/50 and 2011/52. Result = 1000+2000+1500 = 4500
• between 2011/51 and 2012/02. Result = 2000+1500+1200+1700 = 6400

Thank you all in advance.

Answer 1

My steps:

1. Year = A, Week = B, Output = E
2. Create a temp column (C) holding: {Year}*100 + {Week}
3. Create two input sets for the boundaries (also with {Year}*100 + {Week}) — <LOW> & <HIGH>.
4. Create a temp column (D) with this formula:

=IF(AND(C2>=<LOW>,C2<=<HIGH>),1,0)*E2

Then the summation cell becomes:

=SUM(D:D)

EDIT: Found another way with no D column from above

N1 = LOW   (year*100 + week)
O1 = HIGH  (year*100 + week)

N2 => =TEXT(N1)
O2 => =TEXT(O1)

=SUMIFS(E:E,C:C, CONCATENATE(">=", $N$2),C:C, CONCATENATE("<=", $O$2))
