The most beautiful and customizable JSON/JSONP highlighter that your eyes have ever seen. Open source at https://goo.gl/fmphc7

Image from store JSON Viewer

Description from store It is a Chrome extension for printing JSON and JSONP. Notes: * This extension might crash with other JSON highlighters/formatters, you may need to disable them * To highlight local files and incognito tabs you have to manually enable these options on the extensions page * Sometimes when the plugin updates chrome leaves the old background process running and revokes some options, like the access to local files. When this happen just recheck the option that everything will work again * Works on local files (if you enable this in chrome://extensions) Features * Syntax highlighting * 27 built-in themes * Collapsible nodes * Clickable URLs (optional) * URL does not matter (the content is analysed to determine if its a JSON or not) * Inspect your json typing "json" in the console * Hot word `json-viewer` into omnibox (type `json-viewer` + TAB and paste your JSON into omnibox, hit ENTER and it will be highlighted) * Toggle button to view the raw/highlighted version * Works with numbers bigger than Number.MAX_VALUE * Option to show line numbers * Option to customize your theme * Option to customize the tab size * Option to configure a max JSON size to highlight * Option to collapse nodes from second level + Button to unfold all collapsed nodes * Option to include a header with timestamp + url * Option to allow the edition of the loaded JSON * Option to sort json by keys * Option for C-style braces and arrays * Scratch pad, a new area which you can type/paste JSON and format indefinitely using a button or key shortcut. To access type `json-viewer` + `TAB` + `scratch pad` ENTER This plugin is open source https://github.com/tulios Bugs and suggestions https://github.com/tulios/json-viewer/issues Contributors Thiago Pontes (@thiagopnts) @bluec0re @North101 Ben Hollander (@benhollander) Mehdi Bahrami (@mehdibahraami) Reimund Trost (@reimund) Ben van Enckevort (@benvan) License MIT License Any questions tweet me @tulios

(2025-03-12) user chrome: This plugin doesn't work anymore, I use this one [JSON Viewer Chrome Extension] below now, It works pretty well. https://chromewebstore.google.com/detail/json-viewer-chrome-extens/kggkmmjihpjangbkpcdidlhfbnnfaldn
(2025-03-04) Fernando Torres: What happened with the extension? Is outdated at March 3rd, 2025

(2024-07-10) Oleh Ismailov: great tool to view large JSON content
(2024-07-03) Newt Fourie: Great options and great display of JSON in the browser
(2024-05-13) Michael Renper: Utterly useless. Could not figure out how to use it. The description on the Github page is "and here magic happens" - Seem it assume one knows Chrome developer mode. Sorry, I'm a techie but when I want to use a simple tool I do not want to learn 3 other tools first to understand basic usage instruction.
(2024-03-30) Marvin Xu: doesn't work on Edge
(2024-03-24) Herishon Sangma: Very useful tool for viewing json file in web browser
(2024-03-11) Guy DuBoice: It would be nice if google would be upfront about the $5 registration fee. I paid it and I think the extension will be well worth it but having all the information upfront is best practice. Just some feedback.
(2024-03-03) Alen Wede: whats ?
(2024-02-16) Luis Sanchez: Fast and reliable. I love that it handles very large files with ease (even though it warns me that it might not). Thank you to the authors.
(2024-01-24) Mohammad Bozorgmehr: Better performance than JSON Formatter on large responses.

(2023-10-20) Levan Kekelidze: Really useful extension. It has quite flexible configurations, like enabling line numbers, default folding on or off, using different themes etc. Plus it has a search functionality with support of regex, so you can search inside the displayed JSON. Thank you!
