Have you tried this:

From the Excel main menu....
ToolsOptionsGeneral
Check: R1C1 reference style

Does that help?

It's awkward for me to use "A, B, ...CW..." as column names, when large
matrices of data are processed.

I couldn't find a way to change the column name convention in Excel to
regular numbers "1,2,3....", just as the convention of the row names.

Also, I could not find a good reference book, or online reference document,
describing how to rely on numerical references to worksheet locations during
large matrices manipulations. All references I have found a based on "mouse,
click, drag...", which are very impractical for large matrices operation.
