Open JSON File in Windows: 5 Easy Methods September 2025

Want to open a JSON file in Windows but don’t know how? You can open JSON files using Notepad (right-click the file > Open with > Notepad), any web browser by dragging and dropping the file, or specialized tools like Visual Studio Code for better formatting.

JSON files are simple text files that store data, so they work with many programs you already have on your computer. This guide shows you all the best methods to view, edit, and work with JSON files on Windows 10 and 11.


Brief overview of JSON File?

JSON stands for JavaScript Object Notation – it’s just a way to store information in a format that both humans and computers can read. Think of it as a simple text file that organizes data using curly brackets, square brackets, and colons.

Here’s what JSON looks like:

{ “name”: “John Doe”, “age”: 30, “city”: “New York” }

You’ll find JSON files everywhere – from web applications to game saves to configuration files. The good news? Since they’re just text files, you can open them with tools you already have. Many developers use a JSON file viewer to make the data easier to read and understand.

Opening with Wrong Programs

  • Don’t use Microsoft Word
  • Avoid rich text editors
  • Skip programs that add formatting

Encoding Issues

JSON uses UTF-8 encoding. Problems happen when:

  • Files contain special characters
  • The wrong encoding is selected
  • Programs auto-convert encoding

Solution: Always use UTF-8 compatible editors.

Editing Errors

Common JSON syntax mistakes:

  • Missing commas between items
  • Extra commas after the last item
  • Mismatched brackets or quotes
  • Wrong quote types (use double quotes)

Solution: Use validators before saving changes.

Security Mistakes

  • Never run JSON files as programs
  • Don’t trust JSON from unknown sources
  • Avoid online tools for sensitive data
  • Check file extensions carefully

Frequently Asked Questions

Why can’t I open my JSON file in Windows?

Your JSON file might be corrupted or have the wrong encoding. Try opening it with Notepad first – if you see strange characters, the file encoding is wrong. Use a tool like VS Code and change the encoding to UTF-8. If the file won’t open at all, it might be corrupted or not actually a JSON file.

Can JSON files contain viruses?

JSON files themselves cannot contain viruses because they’re just text files. However, be careful with programs that process JSON data. A malicious website could use JSON data to attempt attacks, but the JSON file alone cannot harm your computer. Always download JSON files from trusted sources.

Can I password protect a JSON file?

JSON files are plain text and cannot be password protected directly. To secure JSON data, you can: zip the file with password protection, use encryption software to encrypt the file, store it in a password-protected folder, or use specialized secure storage applications. Remember that once someone opens the file, they can see all the data.

What program opens JSON files by default in Windows?

Windows doesn’t have a default JSON viewer, so files usually open in whatever text editor you have set as default (often Notepad). You can change this by right-clicking a JSON file, selecting “Open with” > “Choose another app,” picking your preferred program, and checking “Always use this app to open .json files.”

Conclusion

Opening JSON files in Windows is simpler than most people think. Whether you need a quick view with Notepad, a formatted display in a browser, or professional editing in VS Code, you have plenty of free options. For open json file windows 11 or Windows 10 users, the built-in tools work perfectly for basic needs.

Remember these key points:

  • JSON files are just text – any text editor opens them
  • Browsers provide free, instant formatting
  • Excel can convert JSON to spreadsheets
  • Online tools work without installation
  • Professional viewers handle large files better

Ready to work with JSON files? Start with the method that matches your needs. For quick viewing, use your browser. For editing, grab VS Code. For data analysis, import into Excel.
