One quick way is to use a pivot table (PT). Insert a top header row, label
in A1: ID, in B1: Days. Then select any cell within the source table, click
Data PivotTable .... Click Next Next. In step 3, click Layout, then drag
n drop ID within the ROW area, drag n drop Days within the DATA area (it'll
appear as Sum of Days), Click OK Finish. That's it.
The PT will be created in a new sheet to the left, with the required
results, eg:
Sum of Days
ID Total
1 13
2 4
3 13
Grand Total 30

Hi there,
I only have 2 columns in my dataset but i have around 40,000 rows so i
need
something relatively quick and easy! ID's are shown in column A and number
of
days is shown in column B, there are duplicate ID's in A. I need to sum B
according to column A (i.e. for ID: 1 i need to add B1 and B2 to equal
13).
Can anyone help me with this?
A B
1 5
1 8
2 4
3 6
3 5
3 2
Thanks,
