- (2025-07-15) Tombkeeper TK: Supports multiple custom configurations, I really like it. It would be even better if indentation lines could be added
- (2024-11-27) Wael Gazia: Very easy and good extensions. I liked the wrap option!
- (2024-11-11) Hugo Moran: Very easy
- (2024-06-10) Guillaume Jobin: Started messing up values whenever I double-click it to select. Seems resolved. Thank you!
- (2024-03-27) Captain_Dada: Very good extension It's indeed very fast even for large files (good for temp large API tests) Maybe you should add a way to add a custom value to the "Auto-format Documents" Another great thing would be a fix for the "Wrap Lines" option cause it doesn't seem to do anything for me (using chromium btw)

- (2023-09-20) Jitendra Dalai: 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.

- (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

- (2019-09-25) 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

- (2019-03-03) 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!

- (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.
