Image from store JSON Formatter

Description from store The original JSON Formatter, now with optional dark mode 🌚 Auto-formats JSON when you load it in a browser tab. FEATURES - Fast, even on very long JSON pages - Dark mode - Syntax highlighting - Collapsible trees, with indent guides - Clickable URLs - Negligible performance impact on non-JSON pages (less than 1 millisecond) - Works on any valid JSON page – URL doesn't matter - Buttons for toggling between raw and parsed JSON Note: this extension might clash with other browser extensions that modify the DOM before it runs. If it doesn't seem to be working, try disabling other extensions. If it clashes with an extension you need, open an issue and I'll try to find a solution. SOME EXAMPLE JSON PAGES to try it out on: https://callumlocke.github.io/json-formatter/ PRO TIP Hold down control (or cmd on Mac) while collapsing a tree - collapses all siblings too. PRIVACY No tracking, no advertising, and nothing else nefarious.

(2023-10-10) Rachel Howell: So good at formatting my JSONs.
(2023-10-08) Gabriel: it does work good when it works. But there is some seriously bad logic on detecting wheter page is json or not, if there is a pre tag that kinda looks like json, it pretty much corrupts a regular html page that has nothing to do with json! The fix is easy, if you dont want to respect the content type tag (which is a form of standard and should be respected, or create a setting for it) then it should not scan page for all <pre> elements but instead check if there is ONLY 1 pre element then consider it, its bad because if a complete html page is perfectly valid and there is a small pre tag in the end of html, it will take that tag and rearrange the html making regular non json pages display incorrectly
(2023-10-06) Noelle Nielson: This is amazing! So much easier than copying and pasting into an online formatter. I didn't realize this was a thing until just barely and it works flawlessly. Makes life so much easier!
(2023-09-25) Carlos Lopez Alvarado: justo lo que buscaba, es muy útil, gracias
(2023-09-06) Prince Ani: Perfect. Makes my work so much easier.

(2023-05-26) Stephen hao: 怎么用呢点击直接跳到github了

(2023-04-28) Zelong Wen: 不错
(2023-04-26) Sangwon Cheon: JSON Prettier 중에 가장 좋은 거 같아요. 이상한 거 집어넣지 않고 광고도 하지 않고, 본질에 충실하네요.
(2023-04-13) Đức Tuấn Minh Nguyễn (Minh): It make my browser (Edge) not responding when get a big json
(2023-03-18) Durganshi Singh: A very light weight and handy tool for developers. I want to give a suggestion. All data type display in same color other than string. If it is possible we can customize colors for specific data types like for numeric field, bool type and null values. It will be very useful for developers.
(2023-03-12) Justin C: It's great, but does not always parse. For example this link: https://www.amazon.com/ap/captcha?appAction=SIGNIN_PWD_COLLECT&captchaObfuscationLevel=ape:c3RhdGlj&captchaType=image&marketPlaceId=ATVPDKIKX0DER&_=1678611210799

(2022-12-20) Maxwell White: Wonderful. I would like to be able to adjust the font-size & colors. Otherwise, lightning fast!
(2022-12-12) Nasreddine El Harcha (Naser): PERFECT with DARK MODE !
(2022-12-12) Ryan Roberts: Works well for small json responses but for anything beyond a moderate size (~100K chars, say an array of ~2000 small objects) the rendering of the json will hold up all of Chrome for all windows/tabs. Had to disable this extension and will selectively turn it on when I need it.
(2022-12-07) Aleksandr Vasilenko: Works great. I use it to view APIs all the time.
(2022-12-06) Aram Sargsyan: Good extension. Thank you

(2022-03-23) Arthur Hoeke: superr
(2022-03-15) Nguyễn Khương: Love at first sight
(2022-03-06) Mikael Dúi Bolinder: I've always been annoyed that browsers format XML but not JSON or YAML, and then I realised that an add-on probably could do it - and JSON Formatter was perfect! Works very well with Microsoft Edge!
(2022-03-03) Yassin Youssouf Ali: I used this extension for about a year, and found it really useful
