In the second step, the columns from the Excel/CSV table are mapped to the fields in CashCtrl.

To do this, simply select the appropriate fields from the dropdowns on the right. Leave the field blank to not import a column.

If you need to create custom fields for information that does not exist by default in CashCtrl, you can click the "Configure custom fields" button at the bottom. After that you can select the custom fields from the dropdown as well.
