Scripts return None when looking for headers "Month" and "Account"

[SgtBatten]

Running python 3.10 on windows 10. Please trust my file names and paths are correct. Somethings not working when it tries to read the CSV as it can't find the headers properly. The budget import step at the bottom reveals it is returning None and i suspect the same issue is causing the problem with the Account splitting.

C:\Users\XXX\Desktop>C:\Users\XXX\AppData\Local\Programs\Python\Python310\python.exe split_export.py RegisterBackup.csv
Traceback (most recent call last):
  File "C:\Users\XXX\Desktop\split_export.py", line 57, in <module>
    main()
  File "C:\Users\XXX\Desktop\split_export.py", line 30, in main
    account = line.pop(account_key)
KeyError: 'Account'

As this failed i did it manually before attempting the budget import below. My transactions in YNAB 4 exactly match my nYNAB history with the only exception being split transactions are not actual splits any more (too many to fix).

This is probably a file encoding issue, which would explain why it only occurs on some operating systems. I don't have access to a Windows system with Python installed at the moment, so somebody else will have to fix this one, I'm afraid. You could start by having the script print the available keys in split_export.py between L29 and L30, probably something like print(line.keys()).
