Importing json files on GUI using python. getting JSONDecodeError

Question

Link to the .json file -> This is the link to the .json file.

I am making a Python based project and what I am trying to do here is to make use of a .json file. However when I tried to import it to use it with the GUI I got the following error.

Thank you in advance. Traceback (most recent call last):

But I have used this file in my other projects. Can you please tell me whether my code is correct? Also I have used the same .json file in other project and it worked. Thank you in advance. — Akshita

Looks like your JSON file is invalid - the sequence of brackets at the end is incorrect.

The end should look like this:

... <previous data> ... ,[2.96361,36.802216]]]}}]}

You can use online or IDE JSON checkers to validate your file.

update

Got your full json file.

It turns out that it has UTF-8 BOM header. Try to load() it this way:

import json
import codecs

data = json.load(codecs.open('tst.json', 'r', 'utf-8-sig'))
print(data)

The example I gave was just an instance of the .json file. The file ends with the brackets in the same sequence you specified.

Error JSONDecodeError: Expecting value means that the JSON is invalid and parser cannot parse it. Can you give us an exact json file, not an example?

I am new to stackoverflow abd I don't know how to attach a file. Can you please help me?
