# Import by ConfigWhen using advanced Excel files (e.g. without any heading columns), it can be complicated to import these.`->byConfig()` will help you handle this problem.Inside `excel::import.sheets` config you can find an example. Excel::load('file.xls')->byConfig('excel::import.sheets', function($sheet) { // The firstname getter will correspond with a cell coordinate set inside the config $firstname = $sheet->firstname; });> **Note:** if you are using multiple sheets. `->byConfig` will loop through all sheets. If these getters are only exist on one sheet, you can always use `->selectSheets()`.
