Parsing JSON with Single and Double Quote in Python

We are given JSON data and we will need to parse JSON data with a mix of single and double quotes. In this article, we will see how to parse JSON data with a mix of single and double quotes.

Example:

Input : '{"name": "John", "age": 30, "city": "New York"}'
Output : John
               30 
               New York
Explanation : Here, we have JSON data with mix doublw and single quote and we parsing it.

JSON Parsing with a Mix of Single and Double Quote

Below, are the methods of JSON parsing with a mix of single and double quotes in Python:

• Using json.loads Method
• Using ast.literal_eval
• Using a Custom Parser

JSON Parsing With A Mix Of Single And Double Quote Using json.loads Method

In this example, the below code uses the json module in Python to parse JSON data stored in the json_data string. The json.loads the method is employed with strict=False to accommodate a mix of single and double quotes in the JSON structure.

Python3

import json

json_data = '{"name": "John", "age": 30, "city": "New York"}'

# Parsing JSON with mixed quotes using json.loads
parsed_data = json.loads(json_data, strict=False)

# Accessing parsed data
print(parsed_data['name'])
print(parsed_data['age'])
print(parsed_data['city'])

Output

John
30
New York

Json Parsing With A Mix Of Single And Double Quote Using ast.literal_eval

In this example, below code uses the ast.literal_eval function to parse a JSON-like string with mixed quotes into a Python dictionary. It then prints the values associated with the ‘name’, ‘age’, and ‘city’ keys from the parsed data, demonstrating how to access specific elements in the dictionary.

Python3

import ast

json_data = '{"name": "John", \'age\': 30, "city": \'New York\'}'

# Parsing JSON with mixed quotes using ast.literal_eval
parsed_data = ast.literal_eval(json_data)

# Accessing parsed data
print(parsed_data['name'])
print(parsed_data['age'])
print(parsed_data['city'])

Output

John
30
New York

Json Parsing With A Mix Of Single And Double Quote Using a Custom Parser

In this example, code defines a custom JSON parser function (custom_json_parser) that replaces single quotes with double quotes in a given JSON-like string. It then utilizes json.loads to parse the modified string into a Python dictionary. Finally, it prints specific values (‘name’, ‘age’, ‘city’) from the parsed data.

Python3

import re
import json


def custom_json_parser(json_data):
    # Replace single quotes with double quotes
    json_data = re.sub(r"\'", '"', json_data)

    # Use json.loads for parsing
    parsed_data = json.loads(json_data)

    return parsed_data


json_data = '{"name": "John", \'age\': 30, "city": \'New York\'}'

# Parsing JSON with mixed quotes using a custom parser
parsed_data = custom_json_parser(json_data)

# Accessing parsed data
print(parsed_data['name'])
print(parsed_data['age'])
print(parsed_data['city'])

Output

John
30
New York
