Who or what is Kate? In what sense is trying to open it any evidence
that it's an Excel file? Did you *succeed* in opening the file "with
Kate"?

What is the problem that the "average user" is having?

Errrrmmm, the "rd" in "xlrd" means *read*  -- it doesn't write files.
For that, you need a version of pyExcelerator (or variant thereof)
with a bug or two fixed. And that won't write "to" files in the sense
of updating an existing file.

Ermmm #2, sense of deja vu here, did you or did you not receive the
detailed e-mail message I sent you 2+ days ago when you first posted??
