By default, the property names of the objects are retrieved from the column headers. Because an object cannot have a blanc property name, only columns with column headers will be imported.

In case you provide more header names than there is data in the worksheet, then all data will be imported and all objects will have all the property names you defined in the header names. As such, the last properties will be blanc as there is no data for them.
