Addin to Visual Studio for visualizing a selected json string in the editor -

I have many XML files, and some elements are embedded, JSON serialized objects are I read and modified Too difficult to do So the question is:

Is there any Visual Studio Edin available, which can pick selected JSN-text in the editor, and imagine it (and maybe even allow editing)?

If not, if I have to make it - are there any good starting points or samples available?

"post-text" itemprop = "text">
