It's a really common use case for me to copy-and-paste some JSON string in a new VSCode buffer, and wanting to see it pretty-printed.
So it's a really common thing for me to change the new buffer's Language Mode to JSON (CMD+Shift+O, type "Language" for Change Language Mode command, type JSON + Enter), then Format Document (CMD+Shift+O, format, Enter).
I'd like to set a new function/shortcut that makes all of that at once. Is there an easy way to do that without writing a whole extension?
