JSON File Extension

Ever seen a file with the File Extension JSON in your PC? Wondering what it’s for or if it’s save to delete it? I don’t usually see this odd file format so I did a bit of research on what it’s for.

The File Extension JSON is a lightweight data interchange format that stands for JavaScript Object Notation. If you open the file using a text editor such as Notepad, you can see that the file is readable similar to XML. The JSON format represents simple data structures and is often used for transmitting structured data over a network connection.

So what application uses the JSON Format? It is commonly used in Ajax web application programming which serves as an alternative to the XML format. If you’re using the Firefox browser, you might see the JSON format being used to store bookmarks.
