The tools we are going to discuss today are designed to help users view JSON files, and some of them will even help with their editing. Now, we should point out that the tools are free to download and use, at least as of this writing.

How to open a JSON file in Windows 11/10

A JSON file is a file that keeps basic data configurations and objects in JavaScript Object Notation (JSON) format, which is a universal data interchange format. It is mainly used for transferring data between a web application and a server. To open a JSON file, you can:

  1. Use Notepad++
  2. Use Microsoft WordPad
  3. Use a7 JsonViewer
  4. Use Online JSON Viewer
  5. Use Firefor.

Let us look at each of these options.

1] Use Notepad++

One of the best Notepad replacement software on the web has to be Notepad++, which has been the case for a very long time. However, this tool is not only a quality Notepad replacement but one that is perfect for viewing JSON files.

Not only can you view JSON files but edit them as well. If you already have Notepad++ installed for the purpose of coding, then there is no need to get something else for JSON.

2] Take advantage of Microsoft WordPad

If you’re not interested in downloading a tool for viewing and editing JSON files, how about using Microsoft WordPad? It’s already available in Windows 10, and it works quite well.

WordPad is a blend of Microsoft Word and Notepad. It doesn’t contain most of Word’s features, but it comes packed with more than Notepad offers.

3] View JSON files with a7 JsonViewer

Another tool we suggest you look at is a7 JsonViewer for Windows devices. From the name, it is clear this is a viewer; therefore, one should not attempt to edit files.

Two of the things we like about a7 JsonViewer are Tree and Text View options. When folks use Tree view, they are basically looking at JSON files from a tree structure view. In terms of text, they’ll be looking at the files in text form.

Download the file from the official website.

4] JSON Online JSON Viewer

If you prefer to view files online, then we believe you will enjoy what Json Online JSON Viewer has to offer. It is as basic as they come; therefore, it is more than good enough for viewing your files.

You have two options for viewing files with this online tool. Either upload your file or get it from a URL.

5] View JSON files using Firefox

Developers tend to use Mozilla Firefox as their default web browser, so it makes sense for the team to add a JSON viewer to the program.

If Firefox JSON Viewer is not working then that post will help you address the issue.

I hope this helps.
