It's a known technique used in many ways, here's another from
Bob Phillips basically using the same technique to get something else

That's quite brilliant.

Would you mind explaining (in English) how this sumproduct is working
please.

I thought sumproduct needed at least a couple of arrays, but this only
appears to have one.

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!
