How to open a JSON file on Windows 10 and 11

You can open a .json file on Windows 10 and 11 with Notepad or a web browser. No extra software needed. Depending on how the file was saved, it might look like a single, massive line of text or a clean, organized list.

JSON (JavaScript Object Notation) is a text format for storing data as name-value pairs and lists. Websites and apps use it to send data back and forth.

Method 1: Open a JSON file using Notepad

Because JSON files are plain text, you can open and edit them with the built-in Windows Notepad app.

  1. Open File Explorer.
  2. In File Explorer, go to the JSON file.
  3. Right-click the file, hover over Open with, and select Notepad. (If you don't see it, click Choose another app and select Notepad from the list).
  4. If you want all JSON files to open in Notepad automatically, click the Always button at the bottom of the window.

If you need a more advanced text editor, I recommend Notepad++. It is a free tool that adds color-coded text and auto-indentation, making long JSON files much easier to read.

Method 2: Open a JSON file in a web browser (Chrome, Edge, Firefox)

If your JSON file opens as one endless, messy line in Notepad, dragging it into a web browser is the easiest way to add spacing and collapsible sections without installing any extra tools.

  1. Open your preferred browser (Google Chrome, Microsoft Edge, or Mozilla Firefox).
  2. Drag your .json file from its folder and drop it directly into a blank browser tab.
  3. The browser reads the file and displays it with proper spacing and indentation. Note: In Microsoft Edge, check the "Pretty-print" box at the top if the text doesn't space out automatically.

People also ask (FAQ)

Why does my JSON file look like a huge block of messy text?

Many JSON files are "minified" to save space. This means all spaces, line breaks, and indentations are stripped out, cramming thousands of characters into a single line. Opening the file in a web browser or Notepad++ restores the readable layout.

Is it safe to open a .json file?

Yes. JSON files are strictly text data files used to store settings or transfer information. They do not contain any runnable code, so opening one in a text editor cannot run a virus or harm your computer.
