• (2022-05-13) Dm. vorTex: WHY JSON Showing on the black field? I don't see anything
• (2022-05-12) Melzz: This is my favourite JSON formatter extension but unfortunately it's not so great when using dark mode
• (2022-05-11) Alexey UIyanov: Looks bad on dark background: color of property names is dark and not changing depends on the theme. So it is not possible to read dark property names on black background.
• (2022-05-10) Danian de Leeuw: Used to work fine but now dark mode ruins it
• (2022-05-10) Patrick Theys: Great extension until latest chrome update running in dark mode.
• (2022-05-10) Roopesh HV: With new chrome update. This formatter is not displaying correctly in darkmode
• (2022-05-09) Benoit Canonne: Fonctionne bien par contre lorsque le mode sombre est activé dans Mac os et donc dans chrome, ça devient illisible, merci d'adapter les couleurs des textes
• (2022-05-09) 辛昕: 为什么在浏览器深色背景下如此难看清楚内容
• (2022-05-09) Chen Mike: Unreadable in DarkMode
• (2022-05-09) Thái Văn Lợi: It's so useful. But I recomment it should has 2 options for user: Dark mode and Light mode. It's so difficult to read when the system is dark mode.
• (2022-05-09) Tihomir Kit: Used to be great. However the project seems to be dead and there are a few bugs which probably won't be fixed. So perhaps just look for a different extension which is still maintained and save yourself some time down the line.
• (2022-05-06) Michael Cyr: Works flawlessly, but with recent update, if you have Dark Mode enabled, the UI goes dark and is nearly unreadable (previously would stay white/default, regardless of browser/system theme). Hoping for a fix soon (toggle or otherwise); not useable in the interim for my purposes.
• (2022-05-06) Tsz-Yan Wong: Has been great until the dark mode came in which made the background dark gray and the text black. Not usable at all until you turn off the dark mode in the os system. I tried to disable Chrome "Force Dark Mode" but it doesn't help.
• (2022-05-04) Ian Tabz: Used to like it before the update, using dark mode the UI used to stay white. Now it's black and I can't read when I'm debugging!
• (2022-04-29) Armin Zheng: can't read key when dark mode open, could fix it? (in Chrome Version 101.0.4951.41)
• (2022-04-21) Guillaume Alpe: Exactly what i wanted to do! Saves me copy pasting to VS Code and formatting there!! Thanks a lot.
• (2022-04-07) Bryan Pereyra: Brutal, super util y facil de usar
• (2022-04-05) Nguyễn Đức Việt Vương: Works wonderfully
• (2022-04-04) Денис Юнусбаев: Быстрый, работает сразу как установил! Спасибо!
• (2022-04-02) Xi Wang: through i download this plugin yet，but when is open it，i redirect to github，not open it。why？

• (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 :)

  App has just stopped working. The page I'm trying to load is pure JSON and isn't being formatted like normal. I see others have mentioned similar. Did a recent release break something?
• (2022-05-14, v:0.6.1) Veeresh Devireddy: Formatting is gone
  After the latest update (a day ago), the Json Formatter extension is broken, which means it is no more showing the formatted json, but like a raw HTML code. Can you please fix it?
• (2022-05-13, v:0.6.1) Brian Wojtczak: Extension Bug introduced with update received today.
  While this extension is great and has been working perfectly for me for ages. Today (13 May 2022) it broke. It looks like a fix which is meant to force light mode made introduced an exception which prevents the extension from running at all. Error in event handler: TypeError: Cannot read properties of null (reading 'setAttribute') at chrome-extension://bcjindcccaagfpapjjmafapmmgkkhgoa/js/content.js:77:64 >> // force to light theme until a dark mode version is created >> document.querySelector('meta[name="color-scheme"]').setAttribute("content", "light");

  For those experiencing the dark mode issue, I created a simple TamperMonkey (extension) script to resolve the issue. Create a new user script, and add the following: // ==UserScript== // @name style-json-formatter // @namespace https://github.com/cookch10 // @version 0.1 // @description custom styling for JSON formatter in dark mode // @author CMC 2017-10-18 11:28:36 AM // @include /^http(s)?\:\/\/.*\.json(\?\=.*\b)?$ // @grant GM_addStyle // ==/UserScript== (function() { 'use strict'; // Hack to fix dark mode for this extension.

  When dark mode is enabled, the background is black and not white. That means that all black text is not visible in the output any longer. You need to detect dark mode or allow users to choose a text color.

• (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

• (2021-07-01, v:0.6.0) Валерий Есипенко: Throw an error if returns combined content but with application/json header
  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.
• (2021-05-27, v:0.6.0) Mahfuzul Amin: Can't click the extension after adding it.
  Hi, I have added the extension and it stays disabled on the extensions list even though it is enabled from Manage extension. Disable and enable doesn't work as well. Any idea? Thanks Mahfuz

• (2021-03-27, v:0.6.0) g r: Not working on localhost
  My served data appears to be in valid json format and its just that inside the body (or a div to try it like that). The extension works on other sites but not on localhost that I'm serving up
• (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.

  This extension is causing chrome to redirect *.mydomain.com URLs to some hotel website (lebua.com) where * is a nonexistent/invalid subdomain. Valid subdomains continue to work as usual. When I uninstall the extension the issue goes away.
• (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
  Is there an option to tell the formatter to NOT drop the decimal values when 0? i.e. I want it to keep the original '40.0' value, I do NOT want it to change it to '40'

I'd just cut out some stuff but without pretty-printing (why I'm running JSON Formatter :-), a bit challenging. thanks, -steve
