This sample data will be for some company “X” with two employees - Jane and Lukas.ĬSV is a data storage format that stands for Comma Separated Values. For consistency, we will look at JSON, CSV, and XML with the same sample data. Now that we know the elements that JSON supports, let’s look at data represented in the JSON format. You can assign data a key and a value, where the value can be any of the above-mentioned data types (string, number, null, etc.).

Objects are the most commonly used data types, and allow you to represent values that are key-value pairs.Arrays are lists that can include any of the above-mentioned types as well as objects (below).Null is another term for “nothing” and communicates that an input has no value.A boolean represents data whose value exists as true or false.A number in a string of JSON data can exist as an integer, decimal number, negative number, or even scientific notation numbers.Strings in complex computer languages and data storage types are usually words.

A string is a sequence of characters that can be a constant or a variable.Here are some of the data types that JSON uses include: To further illustrate this, let’s take a look at the data types (elements) that JSON supports.

JSON files (.json), unlike CSV, which will be discussed later on, have immense nesting and hierarchy features due to its syntax. JSON conversion tools are quite common, and there are many free JSON to CSV format conversion tools out there.Īdditionally, because JSON is derived from the commonly used JavaScript programming language, it can be easily integrated into front-end and back-end development. JSON is also praised for its ability to be easily converted into other formats. More specifically, JSON is preferred for API use, which prioritizes file size due to its lightweight feature. It is often used in conjunction with APIs and data configuration. JSON is known as a light-weight format type and is favored for its readability and nesting features. JSON is a data exchange format that stands for JavaScript Object Notation. This article will compare JSON and CSV, provide explanations of both formats, and briefly explain the XML format. While the above definitions explain JSON and CSV in their briefest form, let's take a closer look at these file types.
