To convert all sheets you must iterate through all worksheets and set it as the active sheet and then write that to a file.
$inFile = 'fileWithMultipleWorksheet.xlsx';
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objPHPExcel = $objReader->load($inFile);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'CSV');
$index = 0;
foreach ($objPHPExcel->getWorksheetIterator() as $worksheet) {
$objPHPExcel->setActiveSheetIndex($index);
// write out each worksheet to it's name with CSV extension
$outFile = str_replace(array("-"," "), "_", $worksheet->getTitle()) .".csv";
$objWriter->setSheetIndex($index);
$objWriter->save($outFile);
$index++;
}

Write each sheet in turn to a different file, and then concatenate those files into one: PHPExcel does not provide an option to write multiple sheets to a single CSV file.
