Cannot get a text value from a numeric cell “Poi”

Question

I'm trying to consume data from a spreadsheet in Excel, but always of this error, already tried formatting the worksheet to text and number and still the error persists.

I saw a person using it resolved cell.setCellType ( Cell.CELL_TYPE_STRING ) ; but I do not know where I fit this passage in my code.

WebElement searchbox = driver.findElement(By.name("j_username"));
WebElement searchbox2 = driver.findElement(By.name("j_password"));         

try {
    FileInputStream file = new FileInputStream(new File("C:\\paulo.xls")); 
    HSSFWorkbook workbook = new HSSFWorkbook(file);
    HSSFSheet sheet = workbook.getSheetAt(0);

    for (int i=1; i <= sheet.getLastRowNum(); i++){
        String j_username = sheet.getRow(i).getCell(0).getStringCellValue();
        String j_password = sheet.getRow(i).getCell(0).getStringCellValue();

        searchbox.sendKeys(j_username);
        searchbox2.sendKeys(j_password);
        searchbox.submit();  

        driver.manage().timeouts().implicitlyWait(10000, TimeUnit.MILLISECONDS);
    }

    workbook.close();
    file.close();
} catch (FileNotFoundException fnfe) {
    fnfe.printStackTrace();
} catch (IOException ioe) {
    ioe.printStackTrace();

Formatter will work fine in this case.

import org.apache.poi.ss.usermodel.DataFormatter;

FileInputStream fis = new FileInputStream(workbookName);
Workbook workbook = WorkbookFactory.create(fis);
Sheet sheet = workbook.getSheet(sheetName);
DataFormatter formatter = new DataFormatter();
String val = formatter.formatCellValue(sheet.getRow(row).getCell(col));
list.add(val);   //Adding value to list
