import xls(x) into org on MacOS

[Uwe Brauer]

Hi

I am usually using Ubuntu 16.04, but for the coming days, I have to use
a MacBook, running 10.15 and fink installed. 
I usually convert xls(x) to org, using 
 '(org-odt-convert-process "gnumeric")
 '(org-odt-convert-processes '(("gnumeric" "/usr/bin/ssconvert %i %o")))


But gnumeric does not exist in fink, does anybody know about an
alternative?
(Yes I know I should have used macports or homebrew, but now it is too
late).

Regards
