Can't open json file to blender using python [duplicate]

Question

I am using blender on windows, following the tutorial: Visualize JSON Data in blender but I am stuck trying to open the JSON file.

My code (windows):

    import json 

    with open('C:\Users\Franktabs\Documents\export.json') as f:
        j = json.load(f)
        print(j)

His code(linux):

import json

with open('/home/chris/Downalds/tutorial.son') as f:
    j = json.load(f)
    print(j)

Error Message:

Python:   File "C:\Users\Franktabs\Documents\Json2.blend\My Script", line 3
     with open('C:\Users\Franktabs\Documents\export.json') as f:
                   ^ SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape
 location: <unknown location>:-1

Solutions Tried:

Using import bpy
Using double \
Using 'r'
Using utf-8
Checking the file type is actually .json
Checking the route and name of the file in properties

Does this answer your question? using backslash in python (not to escape) — Woodford

Backslashes inside a string (such as your Windows path) have a special meaning and must be escaped to be used literally. See the answers to the question linked above for details/workarounds. — Woodford

@OneCricketeer os.path.join is still going to need a base path, which will almost certainly include \U..., which is what is triggering the unicode error. Forward slashes are perfectly acceptable in Windows path literals, and OP claimed to have tried \\ and r literals (which I doubt were done correctly, as they failed, but that's another topic). It's just something else to try without changing the actual code. — MattDMo

As mentioned \U is a unicode escape character, and is likely part of the issue. Without seeing the \\ usage or r'' code or error, hard to know what the issues there could be...

This should work for an OS-agnostic solution, assuming you have a Documents directory where the file exists

import json
import pathlib

with open(pathlib.Path.home() / 'Documents' / 'export.json') as f:
  data = json.load(f)
