We get a data export as a .csv that automatically opens Excel. I've
written/recorded a macro that sets column width, adds header rows and a
footer, changes fonts, and whatnot.

One thing I cannot make it do is insert a graphic of our logo. Any ideas?

In addition to having the graphic as a separate, importable file, I have it
in a template. The problem is that is seems the template only works for new
spreadsheets. It doesn't seem that you can apply it to an open worksheet the
way you can with a style in Word.

Is this graphic thing workable at all?
