Copy and append data from .dat file

You don't show what the line numbers are in run, run_job and run_pending that are involved with the error "PermissionError: [Errno 13] Permission denied". But my best bet is that you had the file open with Excel.
The csv file does not show the columns in Excel? I think Excel expects a semicolon as list separator instead of a comma. This is normal behaviour if you chose "Dutch" in your language settings. Search in your Windows settings for "lijstscheidingsteken". An other way is to execute "data to columns" in Excel.
