I am using PHPExcel to upload data from Excel in Mysql with CI and grocery_CRUD. This is my way:

// My Excel CI Lib

//My Excel CI Model

load->library('Lib_excel', null, 'excel');
        // load excel file
        $objPHPExcel  = $this->excel->load($excelFileName);
        // get active sheets
        $objWorksheet = $objPHPExcel->getActiveSheet();
        // get highest row column
        $lastRow      = $objWorksheet->getHighestRow();
        // check cell value empty or not
        for ($i = $startRow; $i < $lastRow; $i++) {
            $colB = $objPHPExcel->getActiveSheet()->getCell($columnName . $i)->getValue();
            if ($colB == NULL || $colB == '') {
                die('The Cell' . ' B' . $i . ' is empty. Please, remove or fill with data');
            }
        }
        // get excel data with range e.g. (B2:B56)
        $cellValues = $objPHPExcel->getActiveSheet()->rangeToArray("$columnName$startRow:$columnName$lastRow");
        // return all data as array
        return $cellValues;
    }
}
?>

// My Controller to call method

load->model('Mod_excel', 'ModExcel', true);
        // Load CRUD lib
        $this->load->library('grocery_CRUD');
    }
    /**
     * Upload Coupon Code from Excel
     */
    public function createCouponCode() {
        $crud = new grocery_CRUD();
        $crud->set_table('coupon_code');
        $crud->fields('coupon_no');
        $crud->columns('coupon_no');
        $crud->set_subject('Coupon');
        $crud->required_fields('coupon_no');
        $crud->set_field_upload('coupon_no', '../public/uploads/');
        $crud->callback_before_upload(array(
            $this,
            '_excel_uploaded_file'
        ));
        $output = $crud->render();
        $this->_example_output($output);
    }
    /**
     * Call back Function form CRUD Upload
     * @param array $files_to_upload
     * @param array $field_info

     */
    function _excel_uploaded_file($files_to_upload = array(), $field_info = array()) {
        $insert_data   = array();
        $ext           = '';
        $file_tmp_path = '';
        foreach ($files_to_upload as $value) {
            $ext           = pathinfo($value['name'], PATHINFO_EXTENSION);
            $file_tmp_path = $value['tmp_name'];
        }
        $allowed_formats = array(
            "xlsx"
        );
        if (in_array($ext, $allowed_formats)) {
            $excelFileName = $file_tmp_path;
            $columnName    = 'B';
            $startRow      = '2';
            $cellValues    = $this->ModExcel->readWithExcel($excelFileName, $columnName, $startRow);
            $iterator      = new RecursiveIteratorIterator(new RecursiveArrayIterator($cellValues));
            foreach ($iterator as $value) {
                $insert_data[] = array(
                    'coupon_no' => $value
                );
            }
            $this->output->enable_profiler(TRUE); //Turns on CI debugging
            $this->db->insert_batch('coupon_code', $insert_data);
            echo ($status) ? true : false;
        } else {
            return 'Error: Wrong file format. Use Excel 2007 format';
        }
    }
}
?>
