I performed swupd search-files ssconvert
I downloaded some of the bundles that might contain this utility but nothing in the search path.
Is it something I run with “java”?
Here is how ssconvert would be used in bash with input excel files:
for f in *.xls; do
ssconvert -S --import-encoding=ISO8859-1 ./“$f” ./“${f%.xls}.csv”
done
