The currently application allows the user to see the precise PDF page for citation, however, for JSON, it shows the entire JSON file without any highlight. For CSV it simply just downloads the relevant CSV to the user's laptop, not showing anything in the application, could there be a better way to cite JSON/CSV?

It'd be great if we could have better citation rendering for those formats without needing to bring in any additional packages. We already have react-syntax-highlighter for JSON (for our Thought Process tab), so we could theoretically use that for JSON citations.
For CSV, we could perhaps also use that highlighter. We'd also need to change the mime-type, it sounds like.
