View JSON file in Browser

It is not a programming question, but need your views in few words.

When we hit the JSON url in Broswer, it asks us to save the file. Why this happens ? Is there any way to view it on the page itself ? Is there any addon available to view JSON file in browser?

I presume it is IE you are using, if you use Chrome it will show on the page. but if you change the Content-Type: text/html; charset=utf-8 it should allow you to view it in page – Marylinmarylinda 27/3, 2012 at 11:43

@Marylinmarylinda Content-Type of ideal JSON file is always json. It can't be text/html. Do you have any solution for Firefox/IE? Vodun solved it for chrome. – Hypothyroidism 27/3, 2012 at 11:46

Same for firefox: jsonview.com – Fouquet 27/3, 2012 at 11:47

@Umesh Sorry my thoughts on wanting to see the json returned was so you could debug the response, hence changing the response type. i dont try to view my JSON being returned in the browser mostly i just use fiddler to see what is being returned. sorry. – Marylinmarylinda 27/3, 2012 at 11:52

I installed the addon. But it doesn't work for my file - content.dimestore.com/prod/survey_data/4535/4535.json – Hypothyroidism 27/3, 2012 at 11:52

Because the server return invalid "Content-Type: application/octet-stream" should be "application/json" – Fouquet 27/3, 2012 at 11:58

Where "Content-Type:application/octet-stream" is mentioned ? – Hypothyroidism 27/3, 2012 at 12:8

In the http header. You can see it with curl -v content.dimestore.com/prod/survey_data/4535/4535.json – Fouquet 27/3, 2012 at 15:24

@Umesh addons.mozilla.org/en-US/firefox/addon/jsonview for firefox ... added to answer – Barbarossa 27/3, 2012 at 11:53

How to use this add on ? I installed, but when I hit the json url. It saves in browser downloads – Hypothyroidism 27/3, 2012 at 11:53

@Umesh read the help on the plugin page ----> Normally when encountering a JSON document (content type "application/json"), Firefox simply prompts you to download the file. With the JSONView extension, JSON documents are shown in the browser similar to how XML documents are shown. The document is formatted, highlighted, and arrays and objects can be collapsed. Even if the JSON document contains errors, JSONView will still show the raw text. – Barbarossa 27/3, 2012 at 11:54

@ManseUK @Umesh Firefox will still prompt you to download the file if there is a Content-Disposition: attachment response header, even with JSONView. I have added an answer to also view these JSON files in browser https://mcmap.net/q/383396/-view-json-file-in-browser/… – Monovalent 22/8, 2015 at 14:10

@UmeshPatil In Chrome you should just right click by mouse and choose "Open in new tab" at the method which returns JSON data from "Network" -> "XHR" tab of Chrome browser. – Centrality 24/7, 2017 at 6:29

Hi, Is it ok to use this way to process rsponse i angular applications? – Downcomer 25/8, 2020 at 12:56

If you don't want to install extensions, you can simply prepend the URL with view-source:, e.g. view-source:http://content.dimestore.com/prod/survey_data/4535/4535.json. This usually works in Firefox and Chrome (will still offer to download the file however if Content-Disposition: attachment header is present).

+1. Its cool Wladimir. Are there any other prefixes like view-source for FF ? – Hypothyroidism 27/3, 2012 at 13:19

A bunch of them actually but they are meant for internal use - they aren't usually very useful when used manually. – Idette 27/3, 2012 at 14:15

@Umesh: Click "edited ... ago" link to see the change history. I changed the tags - the browser is called Firefox, Mozilla is a company/organization. – Idette 27/3, 2012 at 16:44

+1 for view-source: workaround. But this will not allow you to see the JSON file formatted in your browser with JSONView addon. And if you want to force the browser to open a file with Content-Disposition: attachment response header, you can remove it with moz-rewrite Firefox addon https://mcmap.net/q/383396/-view-json-file-in-browser/… – Monovalent 22/8, 2015 at 14:15

In Chrome, use JSONView to view formatted JSON.

To view "local" *.json files: - after install You must open the Extensions option from Window menu. - Check box next to "Allow Access to File URLs" - note that save is automatic (i.e. no explicit save necessary)

Re-open the *.json file and it should be formatted.

Firefox 44 includes a built-in JSON viewer (no add-ons required). The feature is turned off by default, so turn on devtools.jsonview.enabled: How can you disable the new JSON Viewer/Reader in Firefox Developer Edition?

Well I was searching view json file in WebBrowser in my Desktop app, when I try in IE still same problem IE was also prompt to download the file. Luckily after too much search I find the solution for it.

You need to : Open Notepad and paste the following:

    [HKEY_CLASSES_ROOT\MIME\Database\Content Type\application/json]
    "CLSID"="{25336920-03F9-11cf-8FD0-00AA00686F13}"
    "Encoding"=hex:08,00,00,00

Save document as Json.reg and then right click on file and run as administrator.

After this You can view json file in IE and you Desktop WebBrowser enjoy :)

For Firefox's Bookmarks JSON files, use this excellent Bookmarklet:

javascript:(function(){var E=document.getElementsByTagName('PRE')[0],T=E.innerHTML,i=0,r1,r2;t=new Array();while(/("uri":"([^"]*)")/g.exec(T)){r1=RegExp.$1;r2=RegExp.$2;if(/^https?:/.exec(r2)){t[i++]='['+(i)+']:<a href='+r2+'>'+r2+'<\/a>';}}with(window.open().document){for(i=0;t[i];i++)write(t[i]+'<br>');close();}})();

I have the Content-Type of my JSON-printing CGIs set to text/javascript.

Works fine for both displaying in browser (e.g. Firefox) and processing in script.

Of course there's no syntax-highlighting in this case.

If there is a Content-Disposition: attachment reponse header, Firefox will ask you to save the file, even if you have JSONView installed to format JSON.

To bypass this problem, I removed the header ("Content-Disposition" : null) with moz-rewrite Firefox addon that allows you to modify request and response headers https://addons.mozilla.org/en-US/firefox/addon/moz-rewrite-js/

An example of JSON file served with this header is the Twitter API (it looks like they added it recently). If you want to try this JSON file, I have a script to access Twitter API in browser: https://gist.github.com/baptx/ffb268758cd4731784e3

I would also recommend to use Notepad++ with json-view extension. You get the extension here: https://sourceforge.net/projects/nppjsonviewer/ Install and restart Notepad++. Then open json-file in Notepad and go to "extensions -> Json-Viewer - > Format JSON. Then you habe the hierarchical view of json.

You can also use one of the online-viewers (http://jsonviewer.stack.hu/ , https://jsoneditoronline.org/) which look nice, but I wouldn't recommend this if your data are sensitive in terms of privacy.

For Safari 12 and later, you can try the JSONBeautifier bookmarklet. Also works with other browsers.

I created this because JSON Formatter for Safari stopped working in Safari 12. There are a few new options for Safari 12, but I didn't find an open source one in the App Store, and I do not trust closed source browser extensions.

This can be used as a bookmarklet or the source, json-beautifier.js, can be copied and pasted into the browser console. The code is freely available for review and is less than 100 lines of code including comments. Runs entirely on your device and never sends your data over a network.

Works with local files too. 🤓
