Loved it! I made this version for `fish` and `wl-clipboard`:

    function clipboard-format-json
        # Inspired by https://chris48s.github.io/blogmarks/posts/2021/jsontidy/
        if set -l formatted "$(wl-paste | jq '.')"
            wl-copy $formatted
        end
    end

By saving it to .config/fish/functions/clipboard-format-json.fish, it should immediately work
