Description from extension meta

Makes JSON easy to read. Open source.

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

  • (2023-04-13) 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

  • (2022-12-12) 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.

  • (2022-03-15) 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!

  • (2023-04-13, v:0.7.1) William Bredefeld: problem with content-type
    I notice that json formatting is only triggered when the page's content-type is indicated as json. I often encounter pages with content-type text/html but containing JSON data, and it would have been great if this extension could recognize that it's JSON and still format it.

  • (2022-08-15, v:0.6.2) Kyle Bishop: Thought It Was Broken
    Like many others, I thought a recent Chrome update might have broken the extension, but it turns out that AdBlock was getting in the way. On the site where I was trying to view formatted JSON, I paused AdBlock and my JSON began formatting correctly again. I thought I'd pass this info along so you can broadcast it and save yourself from a million "help it's broken" messages :)

  • (2021-09-24, v:0.6.0) Mathis Neumann: Huge Performance Problems
    Since a few weeks (unsure when exactly), the performance of larger JSON files is abysmal and actually completely blocks the chrome. The initial layout works fine but if I collapse anything, the browser shows the MacOS loading beach ball and is stuck for a long time. This could actually be a Chrome issue if you did not update the extension in the last few weeks...? I use Chrome Version 94.0.4606.61 (Official Build) (x86_64) on MacOS Big Sur 11.4

    Hello, is it possible to throw an error or something like this if page contains combined content, for example <html> + json (php error on page, when it's an php error on beginning of the page and json bellow) but returns content header with application/json value? Now it just hides invalid content and starting to parse with nearest valid token. This behavior don't let to check some api if it works right or not.

  • (2021-03-16, v:0.6.0) Aleksandra Kielian: formatter is rounding big numbers
    I noticed that your formatter is rounding big numbers. For example in the raw feed I can find "ORIGINAL_TRAFFIC_ITEM_ID":3610894680109661683 However if I parse it it is no longer there. Instead it is displayed as: "ORIGINAL_TRAFFIC_ITEM_ID": 3610894680109661700 As you can see the last 3 digits are rounded up to the nearest hundred.

  • (2020-06-29, v:0.6.0) Abhishek Sonone: Big integer Values not parsed correctly
    I've been using this extension for a month. Yeah, it gives me best result. But one issue is there it changes the data if it is too big value. It should not change the data. If we see the same data in Raw mode then it is showing the exact (without modified) data; but when parsed it shows modified. Please look into issue For example: 1101541432344186887 (raw number) parsed to 1101541432344186900 (parsed number)
  • (2020-06-16, v:0.6.0) Kyle Robbins: Decimal values
