FAQ’s About JSON

Python offers multiple ways to pretty print JSON with proper indentation and formatting. Here are the most effective methods:

Method 1: Using json.dumps() (Built-in)

pythonimport json

# Your JSON data
data = {"name": "John", "age": 30, "city": "New York"}

# Pretty print with 4-space indentation
formatted_json = json.dumps(data, indent=4)
print(formatted_json)

Method 2: Using pprint Module

pythonimport json
import pprint

# Load and pretty print
with open('data.json', 'r') as file:
    data = json.load(file)
    pprint.pprint(data, indent=2)

Method 3: Direct File Pretty Printing

pythonimport json

# Read, format, and save
with open('input.json', 'r') as infile:
    data = json.load(infile)

with open('output.json', 'w') as outfile:
    json.dump(data, outfile, indent=4, sort_keys=True)

Key Parameters:

• indent=4 – Number of spaces for indentation
• sort_keys=True – Alphabetically sort keys
• ensure_ascii=False – Support Unicode characters

Advanced Options:

• Custom separators: separators=(',', ': ') for cleaner output
• Remove whitespace: separators=(',', ':') for compact format

Pro Tip: Use indent=2 for web applications and indent=4 for better code readability.
