Try this:
For a DNA sequence in Cell A1
B1: =SUMPRODUCT(CODE(UPPER(MID(A1,ROW(INDIRECT("1:"&LE N(A1))),1)))-33)

Does that help?

I work with DNA and would like to assign numerical values to the bases. i.e.
A = 32 etc.
Ideally, I just want to past a DNA sequence into Excel, e.g. ATGCCA and then
have a numerical display of the value obtained if these are summed. e.g. if
A=32, AA=64, AAA=96 etc.

Any way I can do this?
Thanks!
