The tests don't work and I don't know which bsd license this thing has.
Please help

This library read excel files.

One can write the results in csv format or maybe populate a database.

It provides an example command that prints in csv. I tested it with a
multisheet .xsl document and it worked.

It printed the first line of a sheet along the last line of the previous
one, no separation.

It can provide a list of sheets, so one is supposed to list the sheets,
then extract then one at a time and print them separately by oneself.

Also it doesn't deal with the excel datetime format, which can be
frustrating.
