Let us understand the difference between JSON and XML web technologies. Here’s a brief overview on JSON vs XML with a complete description and examples as well.

让我们了解JSON和XML Web技术之间的区别。 这是JSON与XML的简要概述，并带有完整的描述和示例。

**XML**

**XML格式**

XML is an abbreviation for Extensible Markup Language and was developed by the World Wide Web Consortium.

XML是可扩展标记语言的缩写，由万维网联盟开发。

XML is primarily used to store and transport data from one application to another application over the Internet.

XML主要用于通过Internet将数据从一个应用程序存储和传输到另一个应用程序。

XML format has become a standard for many of the daily tools that we use such as:

XML格式已成为我们使用的许多日常工具的标准，例如：

1.  Open Office
    
    开发办公室
2.  Apple iWork
    
    苹果iWork
3.  Microsoft Office
    
    微软办公软件
4.  LibreOffice
    
    图书馆

The Simple Object Access Protocol (SOAP) widely used XML for inter connectivity and transporting data between multiple applications.

简单对象访问协议(SOAP)广泛使用了XML，以实现相互连接和在多个应用程序之间传输数据。

The file extension for XML documents is .xml.

XML文档的文件扩展名是.xml。

**Example:**

**例：**

XML typically looks like as shown in below example.

XML通常看起来像下面的示例所示。

<car>
       <company>Maruti Suzuki</company>
       <name>Swift Dzire</name>
       <price>800000</price>
    </car>

**JSON**

**JSON格式**

JSON on the other hand is a lightweight data interchange format which is much more easier for computers to parse the data that is being transmitted.

另一方面，JSON是一种轻量级的数据交换格式，对于计算机而言，它更容易解析正在传输的数据。

JSON is developed by Douglas Crockford.

JSON由Douglas Crockford开发。

JSON format is self describing and is comparatively much easier to read than XML formatted documents.

JSON格式具有自我描述性，比XML格式的文档更容易阅读。

JavaScript uses JSON.parse() function to convert JSON formatted string into native JavaScript objects.

JavaScript使用JSON.parse()函数将JSON格式的字符串转换为本地JavaScript对象。

JSON documents are essentially described using Name and Value pairs.

JSON文档实质上是使用“名称”和“值”对来描述的。

The file extension for JSON documents is .json.

JSON文档的文件扩展名是.json。

**Example:**

**例：**

JSON typically looks like as shown in below example.

JSON通常看起来像下面的示例所示。

{
       "company": "Maruti Suzuki",
       "name": "Swift Dzire",
       "price": 800000
    }
