Readig an excel file

Hello I,m reading an excel file, my problem is that when a column is empty i need to capture that value as empty, Im using this function but it jump to the next column if the column before is empty, I need to go column by column and get the value even if it is empty.

fis = new FileInputStream(fileName); // Create a FileInputStream that will be use to read the excel file.
            HSSFWorkbook workbook = new HSSFWorkbook(fis); 
            HSSFSheet sheet = workbook.getSheetAt(0);  
          
          
            
            Iterator rows = sheet.rowIterator();
            while (rows.hasNext()) {
                HSSFRow row = (HSSFRow) rows.next();
                Iterator cells = row.cellIterator();

                List data = new ArrayList();
                while (cells.hasNext()) {
                    HSSFCell cell = (HSSFCell) cells.next();
                    data.add(cell);
                }

Tortuous, but try it like this instead:
while (rows.hasNext()) {
				HSSFRow row = (HSSFRow) rows.next();
				int numCols = (int)row.getLastCellNum();
				//Iterator cells = row.cellIterator();

				List data = new ArrayList();
				for(int i = 0;i < numCols;i++) {	
				    HSSFCell cell = row.getCell(i, Row.CREATE_NULL_AS_BLANK);
				    data.add(cell);
				}
