Deserialize JSON to Object in Python

Deserialize JSON to Object in Python

Last Updated : 07 Jul, 2021

Let us see how to deserialize a JSON document into a Python object. Deserialization is the process of decoding the data that is in JSON format into native data type. In Python, deserialization decodes JSON data into a dictionary(data type in python).
We will be using these methods of the json module to perform this task :

loads() : to deserialize a JSON document to a Python object.
load() : to deserialize a JSON formatted stream ( which supports reading from a file) to a Python object.

Example 1 : Using the loads() function.

Python3

# importing the module
import json

# creating the JSON data as a string
data = '{"Name" : "Romy", "Gender" : "Female"}'

print("Datatype before deserialization : "
      + str(type(data)))
 
# deserializing the data
data = json.loads(data)

print("Datatype after deserialization : "
      + str(type(data)))

Output :

Datatype before deserialization : 
Datatype after deserialization :

Example 2 : Using the load() function. We have to deserialize a file named file.json.

Python3

# importing the module
import json

# opening the JSON file 
data = open('file.json',) 

print("Datatype before deserialization : "
      + str(type(data)))
   
# deserializing the data
data = json.load(data) 

print("Datatype after deserialization : "
      + str(type(data)))

Output :

Datatype before deserialization : 
Datatype after deserialization :
