Hi Bill,

thank you for help. I've tried the filter test. The PDF and Word files run
through the test, but with Excel I've get the following:

$ swish-filter-test http://localhost/test/excel.xls

12319 Warning - http://localhost/test/excel.xls: Use of uninitialized value
in concatenation (.) or string at
/usr/local/lib/swish-e/perl/SWISH/Filters/XLtoHTML.pm line 105.

Document http://localhost/test/excel.xls was  filtered.
   Document:     http://localhost/test/excel.xls
   Content-Type: text/html  (initial was application/vnd.ms-excel)
   Parser type:  HTML*
 
Have you a solution, what could cause this error?

Thanks
Regards
Leo
