Anyone with complex spreadsheets (which is a lot of companies) has a few programmers with the job of maintaining them. The more training those people have in "proper programming" the better the spreadsheets work.

Encoding a program was considered secretarial work, not the act of programming itself. Over time, "encoding" was shortened to "coding."

This is why the industry term "coder" is a pejorative descriptor.
