The main importance of wizards is to simplify the work of the user, so as to avoid complicated entering values and possibly to avoid common mistakes. System wizards are used primarily to create a new system connected to a given external system. The first step is to select the connector you want to use for the connection.

In the case of a CSV wizard, the user does not have to fill in the location of the CSV file on the server, but can simply use the drag and drop zone to upload the file. Another simplification is the selection of the primary identifier, where the user does not have to remember the name of 'columns' in the CSV file, but they are all read from the file and offered in the selectbox.
