Just take this part and put it into a pastebin then do this:
$(user) $(eval $(urlfetch json https://pastebin.com/raw/xxxxxx))
Make sure to include the raw pastebin link otherwise it won’t read properly.
And the json in the urlfetch is necessary. Hope this helped 
and you can format the pastebin with as many new lines as you need and they just get passed over in the eval
Ex. Hi there
Reads the same as
Hi
there
