Catmandu::Exporter::XLS - Package that exports XLS files

       In addition to the configuration provided by Catmandu::Exporter ("file", "fh", etc.) the importer can be
       configured with the following parameters:

       header
           Include a header line with column names, if set to 1 (default).

       fields
           List of fields to be used as columns, given as array reference or comma-separated string

       columns
           List of custom column names, given as array reference or comma-separated list.

       collect_fields
           This  option  will first read the complete stream to create a complete list of fields to export. When
           this option is not set, only the fields of the first record (or the ones  provided  in  the  "fields"
           option will be exported).
