You can also do it with a SUMIF function call...

=SUMIF(A1:A10,"ABCDE*",B1:B10)

(Mat... note the asterisk after the 5 character string you want to sum for)

No need to do that. Use SUMPRODUCT where col A is the co name and col B is
the numbers to be summed.


=sumproduct((left(a2:a22,5)="ABCDE")*B2:B22)

Dear mate,

I have 6000 client names and some are duplicates. I need to copy just the
first 5 letters of each client from the cell and place in the next cell.
This
will help me to sum up all the ABCDE revenue as they are all same client
with
different names with the first 5 letters are common.
Hope I was able to explain my issue,

For example

ABCDE Ltd
ABCDE co.
ABCDE inc
ABCDE ltee

Regards
Mat
