JSON Viewer

JSON Viewer

JSON Viewer is an online, web-based tool that makes it easy to view, analyse, and format JSON data. To view it, simply upload a JSON file or paste JSON code.


All you need to observe how JSON File Viewer functions is your code; it doesn't need any outside resources. The JSON view is used to check the data to see if the value you provided was entered correctly or not. Numerous tools are available for this purpose, but why bother when you can simply enter your code to our online reader and check without downloading, installing, or learning it first?

.The data exchange format JSON (Java Scrip Oriented Language) is used. It employs text and is used to transfer data between platforms, in case you weren't aware. Similar to XML (Extensible Markup Language), JSON is commonly used by computers to convey data, however JSON includes less instances of needless name duplication. It is sometimes referred to as the lightweight exchange format and is simpler for both people and machines to grasp.

All structured data is serialised in JSON and can be represented by two structured kinds and four primitive types, including numbers, Booleans, strings, null, objects, and arrays. A collection of pairs of these strings with values makes up an object, which can include any number of Unicode characters. The JavaScript equivalent of an object is an array, and an array is simply a list of zero or more values. The value must be either an object, number, array, string, or one of the following literal names: false, null, or true.


There are a variety of reasons why using this data-exchanging type would be preferable than using XML. Some of them include:

  • Because there are no additional closing tags in JSON, the file takes up less space than it would in XML.
  • JSON is a more readable format, and the only issue users encountered was having to input extra closing tags, which made it difficult to see the information.
  • JSON employs square and blossom brackets for objects and arrays, making it lighter and contributing to speedier data transmission.
  • Without a doubt, XML is supported by many more apps than JSON, mostly because it is the more established format and is still used today.
  • Coding is not necessary to parse JSON. It doesn't need extra codes as XML and DOM do, which are needed for parsing. How may JSON viewer be useful?


Arrays in JavaScript can also hold a string, integers, objects, Booleans, null values, or other arrays. However, JavaScript allows you to add functions, expressions, and other things. These arrays can store numerous values and have an ordered list of values. You may quickly retrieve an array's values by using their index numbers to make them the value of an object.

While JSON objects are enclosed in curly brackets and include key/value pairs, the value can also be delivered as an array if the value you provided has more categories. The values of objects must be in a proper format, and the keys must contain strings. Key/value pairs are separated by commas, and you can use either dot or square bracket notation to retrieve the values. The name key can be accessed by providing a dot notation, such as x = myObj.Name; for instance, myObj = "Name":"Paul","Age":"20";

Data transmission back to clients is its main goal. Prior to Douglas Crockford's introduction of JSON, XML was frequently used for these web service answers. However, JSON is now preferred for this purpose because it is lighter than the markup language. Data can be stored and transmitted using JSON, and you can also use SQL Server to send and receive data from the internet and other network resources.


To parse and see your JSON files, utilise the Check JSON Online Viewer. You can use our viewer to evaluate your JSON and correct any mistakes you create. The online tool for reading JSON files may also minify your code to make it smaller. You can open a JSON file here and work on it while fixing your mistakes if you need a location to practise. To utilise our JSON tree viewer, follow these steps:

  1. All you have to do is look for the area where it says "Enter or Paste Your JSON" while you are on the JSON Viewer page. This is how the field where you will enter the code looks:
  2. You can either type text into the above area or, if you have the file stored on your computer, upload it. If the file is located on a server, you can also offer a link to it by selecting one of the alternatives that looks like:
  3. And all you need to do to finish uploading the file is hit the "Process" button.
