If you have Excel 2016 installed on your computer, your CSV settings may not be correctly set to split a CSV file based on commas. This may result in all data appearing in one column.

To resolve this:

1. Go to the "Control Panel" of your computer.  
2. Click "Region"
3. Click "Additional Settings" displayed under Date and Time Formats.
4. Enter a comma (,) into the field "List Separator"
5. Click Apply
6. Click OK
7. Click OK
