Hi.
Automic Automation Engine has no built-in facilities for generating Excel files.
You can send mails, including reports, via call objects, or via Automation Engine script, or via calling an external MTU such as sendmail, Postfix, or Powershell. I'm quite sure if you search the forums, you can find specifics about how to send reports via call objects.
You can query the Automic DB for reports with command line database clients, though you'd have to piece the reports together yourself since the Automic DB is not originally designed to be parsed readily by the user. You can probably create Excel files from any input text by using Powershell, should your question happen to concern Windows as a platform.
Beyond that, since you didn't tell us anything about your platform, and quite frankly the details of what exactly you're trying to do still elude me from your original text, these are just some pointers which I hope can point you in the right direction.
Kind regards,
