Preview Option for Custom Report

Hi All,

Does anyone of you know a good solution to preview option to the custom report which is generated from CRM?

in my Instance there are several report and that are generated/ Downloaded from the CRM successfully, but client don't want to download it. They just want to review it, so that they need preview or review option.


Could anybody assist me how to give the view or Preview option to our custom reports.

Any suggestion would be highly appreciated. 

Thanks in Advance
