I am trying to open the JSON file original.json that is outside of my working directory excelTest.py: 
excelTest.pyis in /Documents/Coding projects/pwdemo/pwdemooriginal.jsonis in /Documents/Coding projects/pwdemo
So I've tried to do:
with open("../original.json", 'r') as json_file:
json_data = json.load(json_file)
but I get the following error: No such file or directory: '../original.json'
