In this post we share on json viewers both as online tools and as plugins for browsers and Notepad++ editor.
Online Json Viewer
This is a very convenient online tool for evaluating decoded characters. It also uploads web pictures if the web links are in the text fields, which is a unique parsing feature among other json viewers and parsers. There is, at the same time, a feature to strip the whitespaces and format json variable. 
However, I was not able to upload the json data from the URL. For those preferring the application, there is an application version of this tool with richer functionality; here to download it.
JSONView, the FireFox plugin
This plugin is perfect for highlighting json variables in FireFox. It’s able to fold/unfold multiple elements (not the variable structure). The user rating is high 5/5, but, unlike the previous online viewer, JSONView cannot upload images from the intext links to images.
Online Json Parser
This parser on the French top domain is good for folding/unfolding the variable structure. Besides showing structure and json types (see on the image below), it also evaluates json data, indicating how many elements are present. Showing array indexes is another feature. 
JSON Editor online
This online tool includes all the features mentioned in the previous tools (structure, counting) except for json types and picture showing. It provides the search functionality though. As an editor it allows changing and saving changes. 
JSONView, the Chrome extension
This Chrome extension works perfectly to format json data. It also allows collapsing of the fields.
JsonViewer, the Notepad++ plugin
If you want to view a json variable structure in Notepad++ editor, feel free to install this plugin in the editor. It’s not as rich in features as others, yet it brushes up the json data right in the editor. The data structure of json might be outlined with the next Notepad++ plugin.
JSMin, the Notepad++ plugin
This Notepad++ editor plugin is good in showing the structure of a json variable on the left side panel without formatting json data themselves. This plugin also provides some JavaScript code formatting and minimization.

http://codebeautify.org/view/json is also good one, and it has facility of viewing image.
Link is chnaged to http://codebeautify.org/jsonviewer and it’s awesome site with lots of other json,xml tools loved it.
there are many site providing json to treeview of most easy one is http://jsontuneup.com
like others there have a page able to show treeview and validate json nicely http://jsontuneup.com
http://json2table.com/ is also a good one.
Clean interface and ease to see JSON in table and tree.
http://www.jsview.org is also a decent one. Provides many of the above described features as well.
http://www.jsoneditor.org is a free online tool to view, edit, format, validate and pretty-print json
Is there a way to use any of these online parsers by sending in json text as a post?
So I can just link to the page and it will be populated by my json text rather than having to copy paste?
A nice looking editor from a German company: Inspector Json. https://www.ausdertechnik.de/inspectorjson There is a english version in the Mac App Store. This one fits all my needs.
blinkJ JSON viewer (http://startusingtools.com/blinkj-json-viewer.html) is probably the fastest json viewer that can handle large JSON dataset. I’ve been trying several others but always difficult to handle 50KB dataset. This tool is good with that.
You can also share the content directly with a link. Handy for collaboration.
http://jsonhelp.com/ is also a good one.
Nice formatter, thank you. You might have added storing (browser local Storage or elsewhere) functionality.
I would suggest good tools for JSON Lovers to understatnd JSON data http://jsonformatter.org and http://codebeautify.org/jsonviewer
Found an easy to use formatter but with same features
http://json-formatter.multiutil.com
Nice article Igor. You have nicely plotted the table based comparison of various JSON editors and their features. I have also made a list of 5 best JSON online editor tools here : http://codezag.com/json-online-editor/
You can check and let me know your comments 🙂
Thanks for sharing the links and good article. I would say that there are 2 things which are most signinificant working with JSON:
(1) validating and (2) graphical representation.
The countwordsfree.com/jsonviewer service is also good and it can represent data as XML as well.
Thank you for this links – I am looking for any ideas to improve my project.
I created a json viewer too https://github.com/summerstyle/jsonTreeViewer.
It parses a json-string (by standard browser JSON.parse() method) and display json-data as tree.
The viewer works offline, free and open source. It contains a jsonTree-library, and developers can use it for their projects.
For tabular data, the beset choice by far is http://www.jsondata.ninja
I would suggest good tools for guys to understatnd JSON data http://prettyprintjson.com
I will also recommend a one I wrote for myself, if somebody looks for a windows desktop app for json viewing:
http://jsonviewer.a7.plus
It’s open sourced on github

I recommend this website. We can convert json to many format. http://codeamaze.com/web-viewer/json-viewer
Here is good site, too. http://prettyprintjson.com
I mostly use this tool http://codedestine.com/json-editor.html It has feature to add date and its drag and drop UI makes it easy to construct json. I can also copy and paste whole object into another making it very easy to construct complex json.
Here is good site, too. http://wtools.io/check/validate/json
