App: Free JSON Viewer To Parse and View Your API’s Output

There are times when I’m working with JavaScript Object Notation (JSON) getting passed or returned from APIs and I need to troubleshoot how I’m parsing the array that’s returned. However, most of the time it’s difficult because it’s just a single string. That’s when a JSON Viewer comes in very handy so that you can indent the hierarchical data and then scroll through to find out the information you need.

What is JavaScript Object Notation (JSON)?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of the JavaScript programming language, and is used to represent data structures in a text format that can be sent and received over a network.

Source: JSON

A JSON object is an unordered collection of key-value pairs, where each key is a string and each value can be a string, number, boolean, null, array, or another JSON object. The key-value pairs are separated by commas and surrounded by curly braces {}.

JSON Example

{
  "name": "John Doe",
  "age": 35,
  "isMarried": true,
  "address": {
    "street": "123 Main St.",
    "city": "Anytown",
    "state": "CA"
  },
  "phoneNumbers": [
    "555-555-1212",
    "555-555-1213"
  ]
}

In this example, the JSON object has five key-value pairs: "name", "age", "isMarried", "address", and "phoneNumbers". The value of "address" is another JSON object, and the value of "phoneNumbers" is an array of strings.

JSON is advantageous because it’s easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition – December 1999. JSON is a text format that is completely language-independent but uses conventions that are familiar to programmers of the C family of languages and is natively supported by C, C++, C#, Java, JavaScript, Perl, PHP, Python, and many others. These properties make JSON an ideal data-interchange language.
