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

  • (2021-07-27) Aaron Waruszewski: This is a great app and it still works (tested). To use, open a JSON file in a Chrome tab and it will format it for you. This is for JSON Viewer version 0.18.1 running on Chrome version 92.0.4515.107
  • (2021-07-26) Joseph: I installed and tried on a local file on my computer ==> doesn't work. Maybe restart Chrome? Doesn't work. Reinstall plugin? Doesn't work. Check Json size and increase limit? Doesn't work. Open Firefox without any plugin ==> Works !
  • (2021-07-21) Miguel Gil Rosas: Yes, yes, yes!
  • (2021-07-08) 何晓猛: 主题切换真棒
  • (2021-06-01) Patrik Rufino: Eu instalei, mas depois de alterar o tema para dracula, funciona parcialmente, não fica espaçado e identado.
  • (2021-06-01) Dark theme is awesome. However the integrated search module is worse than Chrome built in search module. Please allow to disable the integrated search. It is making the search function unusable.
  • (2021-04-08) Viet Nguyen: Awesome!
  • (2021-04-08) Seth Fearnside: Works for what I need, so I give it 5 stars!

  • (2021-04-05) Adeonita Sousa: Excelente. Cumpre o prometido
  • (2021-03-25) William LE NORMAND: Working fine but is very slow with big JSON.
  • (2021-03-21) Nataniel Reguła: Looks very well made. It's simple and effective plus it has a large amount of themes.
  • (2021-03-20) Rodrigo Lopes Lameira: Perfeito!
  • (2021-03-05) Gene Yang: 最近发现,空字符串变成了__显示了,这个有点误导,还望还原原本显示。
  • (2021-03-04) Bryce Barbara: Simple and functional. The fact that you edit json to change options is a nice touch.
  • (2021-03-01) Klebson Leite: Antigamente ao clicar no ícone JSON Viewer abria uma aba no browser em que se podia colar um json para formatação e agora não tem mais, é necessario digitar no campo de url do browser `json-viewer` + `TAB` + `json` ENTER, perde-se a produtividade.
  • (2021-02-26) Abdullah Al Mahmud: Very nice and keep up the good work. Thanks!
  • (2021-02-11) Ibrahem: the best

  • (2020-12-30) Thomas Orlita: Really nice, only the "search" feature is annoying, wish it could be disabled.
  • (2020-12-29) Артур Мулюков: После последнего обновления, не конвертирует из php, как можно откатить на предыдущую версию?
  • (2020-12-17) Paul Accisano: Ctrl-F is broken. Unacceptable.
  • (2020-12-13) Sukhy Mann: Love how parameterized it is! I can change my theme, my font, my colors!
  • (2020-12-04) Jonathan Voss: Main drawback is that it is slow and clunky -- large json data sets make it choke up and display incorrectly. It can handle small stuff easily, but it really struggles with anything larger than a small amount of json.
  • (2020-11-18) foolged foolged: Темы это - one love!
  • (2020-11-17) Will Chang: Great work!
  • (2020-11-13) Ciprian Dobrea: straight forward; customizable; love it!

  • (2020-09-30) Ankit Jangid: just 1 question earlier I've tried it worked, but now when i click on extension it opens github page ?

    Hello, There seems to be a large white box at the bottom of the JSON, I have reinstalled multiple times and refreshed but still the same result. The only time it goes away is if the JSON is long enough to cover the entire screen. Screen Shot: https://cdn.tomdeveloper.systems/ad12e82 Thanks, Tom.

  • (2020-08-10, v:0.18.0) James Hill: Bug report - newline inserted when formatting data for Chrome header "sec-ch-ua"
    Hi, I've noticed an issue with JSON Viewer when attempting to format JSON relating to a new header Chrome has introduced recently (sec-ch-ua). Specifically the JSON formatting seems to go wrong when attempting to format this JSON: { "if-none-match": "...", "sec-ch-ua": "\"\\\\Not\\\"A;Brand\";v=\"99\", \"Chromium\";v=\"84\", \"Google Chrome\";v=\"84\"", "sec-ch-ua-mobile": "..." } A newline is mistakely inserted as follows: "sec-ch-ua": "\"\\\\Not\\\"A;Brand\";v=\"99\", \"Chromium\";v=\"84\", \"GoogleChrome\";v=\"84\"", Attempting to format the same JSON in Sublime Text using Pretty JSON: Format and Sort JSON does not cause the same issue. Hopefully this helps you resolve a bug :)
  • (2020-06-01, v:0.18.0) Миша Хантер: Search box position
    The search box position should be fixed at corner of the screen.
  • (2020-05-05, v:0.18.0) Alan Wynn: Option to only show when JSON headers are sent
    Can you please add an option to only show this extension when the "application/json" header is sent? I am a PHP developer, and when I do development (usually within Laravel) I do a DD, this is a die and dump and returns text/html. For some reason your extension always kicks in, and effects the page view for debugging. So an option to only work with the headers would be amazing please.
  • (2019-09-10, v:0.18.0) Stefy Kyra: Improvements
    Hi, this is the best json viewer extension I've used so far, simple and customizable. Few things that I suggest improving: 1) the top right widgets imo should be fixed or at least should have a config so they can be fixed or not; scrolling down through a large json file is somewhat annoying to scroll back up to access the fold or source button, 2) It would be nice to have a collapse/expand button for nested objects (near the fold gutter maybe and configurable); if I want to expand/collapse a specific object with nested properties and leave the others the same can only be done manually with the fold gutter. Keep up the good work!
  • (2019-02-08, v:0.18.0) Yaraslau: Wrong url parsing
    I have an url inside of fson property with params 'platform=ios&region=us' When I open that link in new tab, then 'platform=ios&region=us' is converted into 'platform=ios®ion=us'
  • (2019-01-18, v:0.18.0) Katherine Wolf: How to use
    I installed the extension, but don't understand how to use it. When I click on the icon at the top of my browser window, I just get sent back to the store.
  • (2018-11-12, v:0.18.0) Максим Селивановских: Расширение обрабатывает не JSON
    Непонятно почему расширение вмешивается в простой html: "line1<br>line2" Content-Type: text/html; charset=utf-8 Берет и меняет строки местами, хотя JSON тут и близко нет.
  • (2018-11-09, v:0.18.0) Number of items
    It would be better json viewer to show a number of items when you unfold JSON Object. For example, when you unfold JSON Object of "movies", it now shows like this. "movies": [<->] Hopefully, it changes to something like this format below "movies": [10]
  • (2018-07-06, v:0.18.0) Richard Hanney: Getting it to work...
    Hi, Can not get it to work at all. I've tried loads of json files including reddit but nothing works. I run w10 on chrome 67. Any ideas?
  • (2018-06-05, v:0.18.0) Justin Goltermann: Great extension, but....
    I'm seeing that it adds a <pre> tag to the body of my company's web pages. I get that a <pre> tag might be necessary when rendering JSON text, but this should not be tripping when the content in question is NOT JSON text. Also, it's seriously annoying that this extension overrides Chrome's Ctrl-F shortcut for finding text in-page. DON'T DO THAT! Give it another shortcut, like Ctrl-Shift-F, instead. Other than that, I love the folding, the ability to select color schemes, line numbers & wrapping, etc.
  • (2018-06-03, v:0.18.0) Roman: Unexpected page scroll
    Hello! I have a problem with page scrolling to the very bottom on page load at this website (pages with posts), e.g. https://weblog.west-wind.com/posts/2018/May/31/Web-Code-is-a-solved-Problem-How-about-fixing-Web-UI-next When I'm turning off extension everything works normally. Please confirm & fix the bug. Thanks for the app anyway!
  • (2018-03-28, v:0.18.0) Ivan Djordjevic: Count in search
    It would be great to see how many results are found when searching.
  • (2018-03-28, v:0.18.0) Ivan Djordjevic: Count number of element in a an object
    Just like the count of elements in array, please add support to count the number of key/value in an object itself, so when you collapse the object, you can see the number of elements in it.
