Scheduled Report - Pivot Table as XLS Attachment

Scheduled Report - Pivot Table as XLS Attachment

Hi Guys, 

I was wondering if anyone had a workaround to this problem I am having. Currently, pivot table reports are only allowed as PDF attachments when added as an attachment in the SendMail function (https://www.zoho.com/deluge/help/misc-statements/send-mail.html). Pivot tables can be manually exported as an XLS file - is there any way I can have a pivot table report attached in XLS format in a scheduled workflow?
