How to set default execution of the iHub report to "view as xlsx" instead of html?

Options

Hi Team,

I want to make one of my iHub report (not all reports in iHub) execution to be default view as xlsx. means, if i open/click the report in iHub the output should be display in xlsx by default instead of html. can anyone help me on this requirement?

by default the query sting in the URI has "&__format=html". i want to change this to "&__format=xlsx" dynamically in the report itself by using java script. I need the solution as report specific not environment specific. rest of the reports in the environment should follow the default process - HTML output.

Kindly share your thoughts and solutions...:) :)

Thank you...!!!
