This should a very simple task, surprisingly, I am unable to find any pointers either through search or through Excel documentation. I have two Column in my excel spreadsheet:

A  A111  A222  B  B111  B222  C
2    11   22   3   111   222  -
5    11   22   7   111   222  -
1    11   22   5   111   222  -

I want to create a third column C, which is the sum of the elements in the column A and column B as shown below:


How do I do it in one shot so I generate an entire column ?

Should the value in C (second row) be 12? – dav Jun 18 '12 at 11:23
Sorry but I don't think you've explained it well enough. If you want column C to be A+B, what's the problem with a formula (in R1C1 format as it is easier to understand): =RC1+RC4 Then copy/paste that down the rows. Make the whole table into a list and new rows added will inherit the same formula. Not quite 1 step but close. – Julian Knight Jun 22 '12 at 8:35

You could use the ASCII code and then convert it to a character.


The minus 96 will subtract the characters before the "a".

I don't think he is trying to add non-numeric characters. Although this would work with letters the result of A+B=D – wbeard52 Jun 18 '12 at 4:20
In his post it states A B with a result of C. The char allows letters and numbers. – G Lawlor Jun 18 '12 at 4:23
