Perspective diagram view switch to json view

In 8.1, if it's possible to switch property normal view to json view, how to do that?

Not in the Perspective Property Editor, but you can copy a component or a view and paste it into your favourite text editor.

You'll need to shift click on a view to get Copy JSON option.

It's Shift + Right-click, Copy JSON (third option from the bottom) for a view.
