JSON for academic and research work
Most modern research artifacts ship as JSON: ML experiment configs and results, OpenAlex / Semantic Scholar API responses, survey export files, and increasingly grant proposals (NSF and NIH submission portals export reviewer profiles as JSON). This formatter validates the structure and shows you the shape of the data, key count, max nesting depth, and array count, so you can spot off-by-one issues before pasting into a manuscript appendix.
