Want to note that this extension (a port of Firefox's JSON viewer) seems to work flawlessly (after disabling Orion's current JSON formatting). https://chrome.google.com/webstore/detail/json-viewer/efknglbfhoddmmfabeihlemgekhhnabb
I've tried it on a number of sites (including some larger JSON files) and haven't experienced any issues whatsoever.
Would love to see this viewer brought in as a built-in feature. The source for this port is here, and is MIT-licensed so could be used as the basis for an implementation in Orion: https://github.com/pd4d10/json-viewer
