Converting Python Dict to JSON: Usage of json.dumps() and json.loads()

Last Updated On By

Python Dict to JSON is a very popular data interchange format used for sending and receiving data over the internet. It is primarily used with web applications, but it can also be read by other programs. The JSON file format uses strings to represent objects and arrays. In this blog post, we will discuss how to convert a Python dict object into an equivalent JSON string representation using json.dumps() and json.loads().

JSON - A Popular Data Format for Presenting Structured Data

JSON is a popular data format for presenting structured data. It’s a prevalent practice to transmit and receive data between the server and web application in JSON format.

JSON has several advantages over other formats, including being easy to read by humans, that it can be used with any programming language, that it doesn’t require you to know what types are in your object, and more! In this article we will go through how to parse JSON using Python.

How to Convert Python Dict to JSON?

Python Dictionary is an unordered collection of key-value pairs. JSON (JavaScript Object Notation) is a lightweight data interchange format based on JavaScript object notation. Python dict to json conversion can be done using the following steps:

Step One: Convert Dictionary to String

Use json.dumps() method on the dictionary object, which will return a string representation of that dictionary in JSON format. Below are some examples showing how it works with different types of data including nested dictionaries and lists.

As you can see from above using json.dumps() method, for a dictionary we need to pass string as the first argument and it returns a JSON formatted value.

Step Two: Use json.loads() Method

Now that you have converted your dict into a JSON formatted string using json.dumps(), all you need is to use load() method on this String object returned from json.dumps() method. This will return the Python dict object that you have stored in JSON format.

Example 01: Code

import json
    
dictionary ={
"roll_no": "F16SW-75",
"name": "Anmol",
"department": "Software"
}
    
json_object = json.dumps(dictionary, indent = 4)
print("Data:\n", json_object)

Output

python dict to json

Example 02: Code

import json
    
dictionary ={
    "name" : "Anmol",
    "rollno" : 'F16SW-75',
    "cgpa" : 3.55,
    "ph_no" : "03335556668"
}
    
data = json.dumps(dictionary, sort_keys=True)

print("Data:\n",data)

Output

python dict to json

Conclusion

With this knowledge, you can convert your Python dict object to an equivalent JSON string representation with the json.dumps() and json.loads(). You can also use some of these other functions in order to manipulate your data into new formats that are more readable for humans or machines before converting it back to a dict object using python’s eval function.
