JSON Viewer Plugin for Notepad++ – Features, Download and How to Install

JSON which stands for JavaScript Object Notation is a lightweight data-interchange format. Mostly you would have used it in webservice to send and receive payloads. JSON is based on collection of name/value pairs and ordered list of values.

You can use any text editor even Notepad to create and modify JSON. Smaller files are easy to read and understand. You need a tool for the large and complex one to quickly format and compress JSON.
