Hello @Deekshit P.
Use the Server REST interfaces.
Add a new dashbaord of Dashboards and from the right top side Right Click on ... and select the report and then choose the desired format.
Thanks for replying @Babar
Adding more to the report, I couldn't see the Modified By Information in the "Dashboards".
Can you please help me if there is a way to export the same report with Modified By column also?
