json to xml

What are XML and JSON languages?

JSON is short for JavaScript Object Notation and it is a way to store information in an organized, easy-to-access manner.Json gives us a human readable code of data that human can access in a logical manner.

The following topics are addressed here:

1. JSON Syntax.
2. Data Type.

JSON defines two data structures: arrays and objects.
An object is a set of key and value pairs, and array is a list of values. JSON defines seven value types: object,array, string, number, true, false, and null.

The given example for JSON for the object that contains key and value pairs. The value for the name "firstName" is an object with the value "John" and The value for the name "phoneNumbers" is an array whose elements are two objects.

Sample JSON

          {
            "firstName": "John",
            "lastName": "Smith",
            "isAlive": true,
            "age": 27,
            "address": {
              "streetAddress": "21 2nd Street",
              "city": "New York",
              "state": "NY",
              "postalCode": "10021-3100"
            },
            "phoneNumbers": [
              {
                "type": "home",
                "number": "212 555-1234"
              },
              {
                "type": "office",
                "number": "646 555-4567"
              }
            ],
            "children": [],
            "spouse": null
          }

        

Use of JSON

JSON is often used as common format to serialize and deserialize data in applications that communicates with each other via Internet. These applications are created using different programming languages and can be run in different suitable environments. JSON is suited to this scenario because it is an open standard, Json is easy to read and write and it is more compact than other representations.

RESTful web services use JSON as the format for the data inside requests - responses. The HTTP header is used to indicate that the content of a request or a response is JSON data is:

Content-Type: application/json

JSON representations are usually more compact data than XML representations because JSON does not have closing tags. Unlike XML, JSON does not have a widely accepted schema for defining and validating the structure of JSON data. Thus effectively reduces the length of data.
