I believe what you're looking for is Jq for the json prettifying/manipulation, and nushell for tabular text (not sure about that one, I've only seen it mentioned occasionally).
I strongly believe this should not become the job of the terminal, as it makes it all the more complicated and would possibly deter people from writing the kind of specialized, portable tools that are Jq and nushell for instance.
At most, I think it should be a job for an ncurses application
Everyone is free to not use this feature when it eventually implemented in terminals. Just like syntax highlighting, code completion and AI copilots.
The thing is that as a heavy user I do use jq, terminal triggers and my own stdout colouring/parsing apps that e.g. highlight and parse timestamps or numbers. It all kinda works via endless Cmd+C, "pbpaste | jq" etc but it feels wasteful.
I want to interact with what terminal shows me, not just look at it and copy/paste with broken formatting to somewhere else.
