- (2020-08-11) SnekNOTSnake (Mr Sehat): The developer provides us with two default themes: light and dark. However, we can customize the theme itself. Here, I provide a link to my custom theme (Based on One Dark Pro VSCode theme): https://pastebin.com/qBKvpqyi
- (2019-12-11) Bill Cheng: Really nice and fast. Better than a ton of JSON parser I used.
- (2019-11-07) Derek Lam: Perfect
- (2019-09-25) Boghyon Hoffmann: This is the best JSON viewer I've found so far, in terms of efficiency as well as DX/UX. Unlike other JSON viewers, this extension manages to allocate memory only when it's really needed. 👍 It even supports *.geojson files
- (2019-09-05) inVisement Architect: It works very well. It is light, fast, and minimalist.
- (2019-06-20) SK AZAD: Awesome. Now no need to use other json viewer to simplify the response. Just hit the url in browser and you are done. :)
- (2019-04-05) Георгий Пацер: супер
- (2019-03-03) Julian Knight: Light and fast, gets the job done. Would be nice to have a fold-all option for complex JSON files so that you can start to unfold it from the top.
- (2019-02-22) Hrushikesh Mohapatra: This is the best Json viewer I have come across. I like the "unescape string" feature very much, it helps to read newline formatted long debug info strings.
- (2019-02-21) I've been looking for this extension for a few years. I've used other JSON viewers/formatters and they've all been incredibly slow especially when hiding/revealing branches. I deal with large JSON datasets at my job and this plugin is easily the quickest of all that I have tried. Great job!
- (2019-02-05) The automatic unix timestamp to date display is very helpful.
- (2018-12-21) Lê Công Tuấn Vũ: Please add response status : 200, 400, 500,....
- (2018-12-02) Best JSON formatter for chrome.
- (2018-11-16) Danyel Nanovsky: LARGE JSON FILES - This extension covers them with no hick-up at all!!! Using this more than a year on day to day basis - This is your JSON viewer for Chrome :)
- (2018-09-15) Ali Khosro: Just Works fast and light. Do not forget to enable "allow access to file urls". It gives summary stat, and opens large files when other json viewers fail.
- (2018-06-05) Mikhail Samsonkin: Fast! Thank you very much!
- (2018-05-25) Dan Rynaski: Much faster than other ones I've tried. Thank you!
- (2018-04-26) Taufik Nur Rahmanda: best one, used it on firefox & now chrome
- (2018-03-31) Guy Kawasaki: Super fast even on large documents!!!
- (2018-01-22) Chandrashekar Chimbili: Tried many json formatter extensions. The best I have used so far. Keeps the view simple. Like it!!
- (2017-06-28) Ruud: A raw view would be nice. But even without it, this JSON viewer is already the best.
- (2017-03-28) Chris Berry: Hands down the best JSON viewer plugin I've found. Super performant for large documents.
- (2017-01-19) Theodore Tucci: 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.
- (2016-10-24) Jason: very fast. good.
