Data send and get generally in a string of dictionary(JSON objects) forms in many web API’s to use that data to extract meaningful information we need to convert that data in dictionary form and use for further operations.

Let’s see some ways to convert string to json.

Method #1: dict object to string object using json.loads




# Python code to demonstrate
# converting string to json 
# using json.loads
import json
  
# inititialising json object
ini_string = {'nikhil': 1, 'akash' : 5
              'manjeet' : 10, 'akshat' : 15}
  
# printing initial json
ini_string = json.dumps(ini_string)
print ("initial 1st dictionary", ini_string)
print ("type of ini_object", type(ini_string))
  
# converting string to json
final_dictionary = json.loads(ini_string)
  
# printing final result
print ("final dictionary", str(final_dictionary))
print ("type of final_dictionary", type(final_dictionary))

Output:

initial 1st dictionary {'manjeet': 10, 'nikhil': 1, 'akshat': 15, 'akash': 5}
type of ini_object <type 'str'>
final dictionary {'nikhil': 1, 'manjeet': 10, 'akshat': 15, 'akash': 5}
type of final_dictionary <type 'dict'>

Method #2: str object to dict object using eval()




# Python code to demonstrate
# converting string to json 
# using eval
  
  
# inititialising json object string
ini_string = """{'nikhil': 1, 'akash' : 5,
            'manjeet' : 10, 'akshat' : 15}"""
  
# printing initial json
print ("initial 1st dictionary", ini_string)
print ("type of ini_object", type(ini_string))
  
# converting string to json
final_dictionary = eval(ini_string)
  
# printing final result
print ("final dictionary", str(final_dictionary))
print ("type of final_dictionary", type(final_dictionary))

Output:

initial 1st dictionary {'nikhil': 1, 'akash' : 5, 'manjeet' : 10, 'akshat' : 15}
type of ini_object <class 'str'>
final dictionary {'nikhil': 1, 'manjeet': 10, 'akash': 5, 'akshat': 15}
type of final_dictionary <class 'dict'>
