JSON Viewer

JSON VIEWER – NO EXTERNAL APPLICATIONS REQUIRED

JSON File Viewer doesn’t require any external resources, all you need is your code, and you will be able to see how it works. JSON view is used for verifying the data that the value you gave is written correctly or not. There are many programs used for this purpose but why bother download, install and learn it first when you can just add your code to our online viewer and check.

JSON (Java Scrip Oriented Language) is a data interchange format. If you aren’t aware, it uses a text format and is used to exchange data between platforms. It is widely used today by systems to communicate data just like XML (Extensible Markup Language), but JSON has less the unnecessary repetition of names. It is also known as the lightweight version of interchange format and is easier to understand for humans and machines.

In JSON all the organized data is serialized and can represent four primitive and two structured types which are numbers, Booleans, strings, null, objects and array. A string can contain any number of Unicode characters, and an Object is a collection of pairs of these strings with values. An object and array are similar to the one used in JavaScript, and an array can be described as a sequence of zero or more values. The value must be one of the following literal names (false, null, true) or objects, number, array, string.

WHY PREFER JSON OVER XML ?

There can be many reasons why one would want to use this data interchanging type and why it is better than an XML. A few of them are:

• JSON uses less space than XML by eliminating extra closing tags which also results in less occupying of space by the file.
• JSON is a more readable style, and the only problem people had to face was when they had to type extra closing tags thus making the values a little tough to read.
• JSON uses flower and square brackets for objects and arrays which also makes it lighter and is a reason for faster transmission of data.
• No doubt XML is supported by many more applications than JSON, and that’s mainly because it’s the oldest and people still practice it.
• JSON does not need code to parse. It doesn’t need additional codes for parsing like XML requires extra codes and DOM for parsing. How JSON viewer can help?

HOW OBJECTS AND ARRAYS WORK AND WHERE CAN JSON BE USED?

Arrays are similar to the ones in JavaScript and can hold a string, numbers, objects, Boolean, null or extra arrays, but in JavaScript, you can add functions, expressions and more. These arrays include an ordered list of values and can store multiple values. An array can become a value of an object, and you can easily access them using an index number.

Whereas curly braces surround JSON objects and contain pairs of key/value, where value can be provided in an array as well, and if the value you gave has more categories then an array is used. The keys in objects must carry strings, and the values must be in a valid format. A comma separates key/value pairs, and if you want to access the values, then you can either use a dot or a square bracket notation. For example myObj = {“Name”:”Paul”,”Age”:”20”}; the name key can be accessed by entering a dot notation like x = myObj.Name;

Its primary purpose is to transmit data back to clients. Previously for these web service responses XML was widely used, but since JSON got introduced by Douglas Crockford, it is the format preferred for this motive because it’s lighter than the markup language. JSON is used to store and transmit data, you can use it to transmit data within applications, and SQL server allows you to transmit and receive data from the web and network resources.

HOW TO VIEW JSON FILES USING OUR ONLINE JSON VIEWER?

You can use Check JSON Online Viewer to parse and view your JSON files. Our viewer will help you validate your JSON and help fix any errors you make. Read JSON File online tool can minify your code for decreasing the size of your file as well. If you need a place to practice, then you can open JSON file here and work on it while taking care of your errors. Follow the below steps to use our JSON tree viewer:

1. When you are on the page of JSON Viewer all you have to do is look for where it says “Enter or
   Paste Your JSON”. The field where you will enter code looks like this:
2. You can either enter text into the above field, or you can upload a file if you have it stored on your computer else you can provide a link to that file if its present on some server by clicking on the options that look like:
3. And when you are done uploading the file all you have to do is tap on the “Process” button as shown in the picture below:
