sys.exit("error: invalid sheet delimiter\n")

In previous versions it was allowed to have "-s multi-character-string" as a sheet delimiter but has since rejected as invalid in more recent versions, any reason to not allow it like was previously supported?

Very useful script and it has made my life easier for some work tasks, keep on keepin' on either way.

I don't see any reason why this restriction is needed, it was added 9 years ago

The version checked into our repo was from 2011 heh, we didn't have an issue with it until now and whatever you did between then and now fixed it so... keep up the good work.
