Error string indice must integers Json

[snippsat]

Use code tag
Don't use decode of json.load() with Requests,theses are build into Requests.
Example:

import requests

url = 'https://api.github.com/'
url_get = requests.get(url)
json_data = url_get.json()
print(url_get.encoding)
print(type(json_data))
# Parse json
print(json_data["current_user_url"])

Output:
utf-8
<class 'dict'>
https://api.github.com/user

Error:
TypeError : string indices must be integers

That's a common error message because in a larger json usually also a get back list in the dictionary.
So it normal to parse like this.
json_data['something'][0]['CL_NOME']
