JSON is a lightweight data-interchange format that is easy for humans and computers to understand. It was created by Douglas Crockford in 2001 but was first introduced as part of JavaScript. JSON has been widely adopted since it was created as it can be used across multiple programming languages.
In other words, JSON (JavaScript Object Notation) is a lightweight data-interchange format that makes it easier for web developers to handle the process of uploading and managing dynamic web content without having to worry about internal complexities such as the parsing of XML or the conversion of objects into strings, which can lead to errors when processing the application.
JSON Tree Viewer is an online web application that enables users to explore any JSON file in a tree view. This tool provides options for better viewing the code or making JSON viewer work offline.
