Question

Below is what I have.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+  A  +  B  +  C  +  D  +  E  +  F  +  G  +  H  +  I  +  J  +  K  +
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
+  1  +  2  +  3  +  4  +  5  +  6  +  7  +  8  +  9  +  10 +  50 +
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

To find the SUM of this row excluding Cell E I am using formulae as below.

=SUM(A1:D1)+SUM(F1:J1)

NOTE : Cell K have SUM.

Is there any alternate way??

Above is just an example however in my sheet there are around 100 columns and I need to exclude around 10-15 columns.

Answer 1

If you add a row like this:

Row2: yes yes yes yes no yes yes yes yes yes no ...

(being columns A:K)

Then the answer could be

=SUMIF(2:2,"yes",1:1)
