entering header row settings

This step requires you to define an option that will regulate the way data in the first row of the selected range will be treated.

Column headers are the field names that Labeljoy will use to identify the data.

If you leave the default option, Labeljoy will read data from the top row and use it as field names, without including it in the set of records that can be displayed on labels.
If you choose the second option instead, all data will be available to label elements and the fields will be given automatic names (F1, F2, F3 and so on).
