Hello @Kalyan_reddy, unfortunately, there is not a way to retrieve a theme from the Demo Central page. Themes can be shared within a single QuickSight account, so those themes are not available in your account. As for number of themes per account, you can build however many you want! I am not sure if there is a limit to the number you can create, but you can only use a single theme per dashboard. It isn’t something that can be different between each sheet.
