I don't think it is quite so simple: (and
parse_doc and conv_doc) only use the "magic number" of the
file to decide which utility to use for conversion.

MS Word and Excel files can have the same magic number.

The easy solution is a separate conversion script for excel
files. The sophisticated solution is a more advanced
script which uses the information on MIME type passed to it.

I hadn't heard of xlHTML and would like to know more.
As an alternative, there is a simple .xls to .csv
conversion program available from the same site as catdoc.
