[Tkinter] How to insert data json to treeview tkinter?

[Shakanrose]

Hello, thank you for your answer.

If I put the following code, I can see the data I need in the terminal, but I don't know how to pass it with the treeview.insert() to my treeview table.

import json

with open('personal.json') as fp:
        data = json.load(fp)
 
for element in data['Clientes']:
     print(element)

Now, if I put it the way you showed me, it tells me the following.

Error:
AttributeError: 'str' object has no attribute 'items'
