Overview
Once a step has been configured in the transformation flow, data will appear in the data preview panel in the form of column fields. You can then convert the datatype data type of a field into something that suits your requirements. For example, text can be converted into numeric values, SQL date, or SQL timestamp.
This type of transformation is done directly on the data in the data preview panel. Click on the drop down icon next to a field’s datatype data type and select the target data type.
