In this article, we’ve learned how to handle JSON data in MongoDB and the various operations that can be performed on JSON using MongoDB. The field names and values are separated by a colon, the filename-value pairs are separated by commas, and a set of records are enclosed in curly brackets. Let’s structure the table above in JSON format bearing in mind that JSON is formatted as name or key-pair values. db.students.find().pretty() As you can see in the screenshot below that the documents are in JSON format.

What makes it easy to access data is its set of various tools to export and import JSON documents between systems. JSON can store various data types like strings, arrays, objects, and Binary JSON (BSON). For these reasons, JSON has a wide range of applications in programming and data representation. JSON is simple and easy to use besides being independent of any language. JSON objects can easily get transferred from one system to another due to their compatibility with the majority of systems. JavaScript Object Notation (JSON) is a data exchange format solely based on JavaScript. MongoDB has grown in its use due to the scalability and its ease of use.
