Automatically parse json with additional curly braces

[mileaminute]

When pasting json into Notepad++ it will sometimes be copied with the json wrapped in additional curly braces, like this:

{{json}}

If I delete the extra brackets, I can transform with the plug in. It would be more difficult to copy the json without the extra braces. Request is to simply autostrip the extra braces before converting to avoid the Error 4: Missing a name for object member. Thanks.
