How to Open JSON File? (original) (raw)

Last Updated : 23 Jul, 2025

JSON (JavaScript Object Notation) is a lightweight, text-based data format that stores and exchanges data. Let's see how we can create and open a JSON file.

**How to Create JSON Files?

Before learning how to open a JSON file, it's important to know how to create one. Below are the basic steps to create a JSON file:

• Open a text editor on your computer (such as Notepad, TextEdit, or VS Code).
• Create a new file.
• Save the file with the .json extension (e.g., sample.json).
• Copy the following sample JSON code and paste it into your file, then save it again.

**Sample JSON File

JavaScript `

{ "name": "Amit Kumar", "age": 30, "city": "New Delhi" }

`

**Open JSON Files

1. Opening JSON in a Text Editor

If you want to quickly view or edit a JSON file, a text editor like Notepad, Visual Studio Code, or Sublime Text works best.

• **Windows/Mac: Right-click the JSON file and choose "Open with" > "Notepad" or your preferred text editor.
• **VS Code: Open VS Code, click on "File" > "Open File," and select your JSON file.

**Advantages

• Simple and fast
• Good for quick edits or viewing

2. Opening JSON in a Web Browser

Browsers like Chrome and Firefox automatically format JSON data in a readable way, making them a great option for viewing JSON files.

• **Chrome/Firefox: Drag and drop the JSON file into the browser window or use Ctrl+O (Cmd+O on Mac) to open the file.

**Advantages:

• Instant visualization
• Clean formatting for better readability

3. Opening JSON with Python

Python has built-in support for reading JSON files. You can use the json module to load the content into Python objects.

Python `

import json

Open the JSON file

with open('path/to/your/file.json', 'r') as file: data = json.load(file)

Print the data

print(data)

`

The json.load() method reads the content and converts it into Python objects (like dictionaries and lists).

**Advantages:

• Ideal for processing and manipulating JSON data
• Easily integrated into applications

4. Opening JSON with JavaScript

JavaScript is another great tool for working with JSON files, especially for web developers.

JavaScript `

fetch('path/to/your/file.json') .then(response => response.json()) .then(data => console.log(data)) .catch(error => console.log('Error:', error));

`

• The fetch() method makes an HTTP request to load the JSON file, then the .json() method parses it into a JavaScript object.
• Perfect for web applications and dynamic data handling
