Follow-up Comment #1:

Good catch!

I rarely use xlswrite myself, I only supplied it for the Matlab-compatibility
seekers :-)   I rather use xlsopen-oct2xls-xls2oct-xlsclose sequences.

Anyway I'll fix this in svn. Note that the line should rather be

if (strcmpi (filename(end-3:end-1), "xls"))

because you can also (try to) write .xlsb, .xlsm and some other .xls? types.
Whether that will ever be implemented in lower functions is uncertain, but
xlswrite.m shouldn't be a limiting factor.
Within one or two weeks I hope I can make a new io package release (probably
end of April / early May); it'll contain this fix.

I've also applied the fix i xlsopen.m and private/spsh_chkrange.m

Thanks

(OS changed to "any")
