For some reason, the file Intuit provides (\*.xlsx) is not in the correct format for importing and needs to be adjusted.
After downloading the [file](https://intuitproadvisorstorage.blob.core.windows.net/$web/filestore/documents/Bank_rules_file_22.xlsx), you will need to find it on your computer (likely in your Downloads folder), open it, enable editing, then save as in the "Excel 97-2003 Workbook (\*xls)" format.
This newly saved file is the one you will import later in the exercise.
