JSON (JavaScript Object Notation) is a lightweight data exchange format. Easy for humans to read and write. It is also easy for machines to parse and generate. It is based on JavaScript Programming Language, a subset of Standard ECMA-262 3rd Edition – December 1999. JSON uses a completely language-independent text format, but also uses conventions similar to the C language family (including C, C, C#, Java, JavaScript, Perl, Python, etc.). These properties make JSON an ideal data exchange language.
When using the struts2 json plugin to convert relevant data objects into json data and send it to the front page, it is often too difficult to troubleshoot errors due to the excessive amount of data. Therefore, here are several tools for viewing json data to help form a Tree and facilitate data browsing.
Json Viewe
This tool provides 3 options:
is an independent exe file, you can click to view the json object directly;
Fiddler [a free proxy that records host HTTP (S) communication] plug-in
Visual Studio 2005 plug-in.
JSON plug-in for Eclipse: JSON2XML TreeViewer plugin for Eclipse
The main function of this plug-in is to convert json data into Json Tree and Xml Tree, and test it using eclipse When coding, copy and paste the generated data directly into this tool, eliminating the pain of opening a new software. Isn’t it very convenient to operate?
Just put the jar package into the elipse plugin, restart elipse > Click show view in the lower left corner > Find Json analyzer, double-click to add.
Firefox’s json plug-in
With this tool, you can view JSON like an XML file in FF browser, with automatic code highlighting and automatic indentation , automatic folding function. Even if there are errors in the JSON file, JSONView can still display the original code.
After installing JSONView, please go to http://brh.numbera.com/software/jsonview/example.json to view Does the expansion work? If you can see the folded tree, it means it is OK.
You can choose the above three tools as needed, which can basically meet the needs of daily JSON data viewing.
I recommend a useful online JSON structure observation tool.

The editing tool does not recognize the single quotes of key/value. You must manually replace the single quotes with double quotes, otherwise an error will be reported.
