JSON in place with IE

How many time have you tried to do a REST call in IE expecting to display the JSON data but the browser IE has prompted to download it?
To me, too many!

The solution to this problem is to update the registry telling IE that for docs that have a mime type of application/json, just view it in place. This won't affect any application/json documents downloaded via script tags, or via XHR, and so on.

How it works

Stop IE. Then, cut and paste the following into a file, by the name of json.reg.
 

 Windows Registry Editor Version 5.00  
 ;  
 ; Tell IE to open JSON documents in the browser.   
 ; 25336920-03F9-11cf-8FD0-00AA00686F13 is the CLSID for the "Browse in place" .  
 ;   
 [HKEY_CLASSES_ROOT\MIME\Database\Content Type\application/json]  
 "CLSID"="{25336920-03F9-11cf-8FD0-00AA00686F13}"  
 "Encoding"=hex:08,00,00,00  
 [HKEY_CLASSES_ROOT\MIME\Database\Content Type\text/json]  
 "CLSID"="{25336920-03F9-11cf-8FD0-00AA00686F13}"  
 "Encoding"=hex:08,00,00,00  

Then double-click the .reg file and restart IE. Eventually the response you will have for Content-Type: application/json or Content-Type: text/json will be correct.

 }  

For Chrome and FF it is more simple: just download the add-on JSON Viewer!
FF: https://addons.mozilla.org/it/firefox/addon/jsonview/
Chrome: https://chrome.google.com/webstore/detail/json-viewer/gbmdgpbipfallnflgajpaliibnhdgobh

Enjoy!
