Not able to open or manage JSON files on your Windows device? Well, do not worry; this guide will explain what a JSON file is, how to open them, and what to do in the case of improper functioning of the files.

What Type of File Is a JSON File?
JSON (JavaScript Object Notation) is a lightweight text format that stores structured data for data interchange. Its use covers sending data from the server to the web applications. A JSON file is both human- and machine-readable; hence, versatile in that it is readable by developers and the end-user himself.
How to Open JSON Files?
You can open JSON files in simple text editors or specialized applications. Basic tools like Notepad or WordPad work well for viewing, while advanced editors such as Notepad++, Visual Studio Code, or Sublime Text allow deeper editing and extended use.
These provide features like syntax highlighting to make JSON files easier to work with.
What to Do If You Can’t Open a JSON File?
If you’re unable to open a JSON file, it may be due to incorrect file associations or missing software. Follow these solutions to resolve the issue:
Solution: Use the Right Program to Open Your JSON File
Ensure that you’re using the correct program for your JSON files. Programs like Notepad++, Visual Studio Code, and Sublime Text are excellent for editing and viewing JSON files.
