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
import json
data = '{"Name" : "Romy", "Gender" : "Female"}'
print ( "Datatype before deserialization : "
+ str ( type (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
import json
data = open ( 'file.json' ,)
print ( "Datatype before deserialization : "
+ str ( type (data)))
data = json.load(data)
print ( "Datatype after deserialization : "
+ str ( type (data)))
|
Output :
Datatype before deserialization :
Datatype after deserialization :
