Much faster than other ones I've tried. Thank you!
best one, used it on firefox & now chrome
Super fast even on large documents!!!
Tried many json formatter extensions. The best I have used so far. Keeps the view simple. Like it!!
Super json viewer. All the things you want at a place. The current Google Chrome update to v. 117 spoils everything. json-lite not working anymore.
A raw view would be nice. But even without it, this JSON viewer is already the best.
Hands down the best JSON viewer plugin I've found. Super performant for large documents.
Though there may only be five reviewers so far, this is the best JSON viewer available. All of the other JSON viewers lag or have issues but this one loads up even the largest of requests from my API flawlessly without any lag. Only thing that could make this better is if there were a switch to view in either RAW format or Prettified JSON.
very fast. good.
