AI 产品解读A fast, lightweight JSON/JSONP viewer and formatter for Chrome that replaces the browser's default raw JSON display with a syntax-highlighted, collapsible, interactive view.
Reading and navigating raw JSON responses in the browser is difficult, especially for large files. This extension automatically formats JSON with syntax highlighting, collapsible arrays/objects, item counts, and size indicators, making JSON data human-readable and navigable.
User navigates to a URL returning JSON (or JSONP). The content script detects JSON content, sends a message to the background service worker which injects CSS and executes a formatting script on the page. The raw JSON is replaced with a syntax-highlighted, collapsible tree view. User can customize appearance and behavior via the options page. Context menus allow formatting/encoding/decoding selected text on any page.

- Web developers / API developers / Data analysts / Anyone working with JSON data in the browser
- No network calls or external services to verify — extension is entirely client-side which makes analysis straightforward but there's minimal dynamic behavior to confirm

- No authentication, account creation, or login flow exists anywhere in the extension. All preferences are stored locally via chrome.storage.sync/local with no remote account. The extension operates entirely client-side on the user's browser.
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.
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.
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!
The automatic unix timestamp to date display is very helpful.
Please add response status : 200, 400, 500,....
Best JSON formatter for chrome.
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 :)
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.
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
Fast! Thank you very much!
