- (2025-03-26) James: Use it daily, kodus to the developers
- (2025-02-27) Marufjon Saidov: it's veri good extension
- (2025-01-13) Kokoy Labaymimi: very recommanded, I use it all the time
- (2024-10-30) Moana Wong: As I understand, you need to be on content-type 'application/json' document. And then allow the plugin to parse it by clicking on the plugin icon , select "This can be read and change site data", then select among 3 options : - "When you click the extension" - "On < example-website.com >" - "On all sites" If not on a JSON document, all parsing and reading is disabled by default which may seem like this extension is not working, but is !!
- (2024-08-07) ArchSinccubus: It just... Doesn't work? I press the button, like the instructions say, and... Nada. No download, not even a bar or any indication that anything happens. Shame, I was hoping it would help me

- (2023-08-28) Wesley Schwengle: They changed the UI. I don't like the current way. I need to flip the prettify the JSON everytime I refresh the page. I also miss the ability the fold/unfold the JSON. It went from very usable to nice MVP. Would not recommend it anymore.

- (2022-09-23) Chester Yu: Generally great tool. Would be great to have default style for dark mode and auto switching.

- (2022-01-27) Lindsay Frost: Added extension with a click. Tried it on new openAlex interface with JSON response (e.g. https://api.openalex.org/authors/https://orcid.org/0000-0001-6187-6610 ) and it worked fine! My system has Chrome Version 97.0.4692.99 (Official Build) (64-bit)

- (2021-12-03) George Pantazes: I liked and used this extension for a while, but some things annoyed me: - The rendered JSON cannot by copied as raw JSON text. It strips off all of the quotes, meaning you have to flip back to RAW if you want to copy valid JSON. - The button to switch to raw text doesn't work for me. I had to disable the extension entirely to see the underlying raw JSON. Until the above issues are addressed, this plugin is fine for simply viewing JSON, but that's where its usefulness ends. However, since it doesn't allow copying valid JSON or flipping back to the raw text, it often creates problems when switching over to heavier tools such as a text editor. I'll be switching to and trying out the JSON Viewer extension (https://chrome.google.com/webstore/detail/json-viewer/gbmdgpbipfallnflgajpaliibnhdgobh) instead, which doesn't suffer from the above issues, and still has features like syntax highlighting and collapse/expand.
