Reading Excel file with Scala

I am writing a quick test that registers a user with the data from a spreadsheet.

The idea is Go to the website > click register > Read excel rows A1 and B1 for email and password > use this data on registration site> finish the registration > log out > Register a new user with information from rows A2 and B2 > continue until rows in the spreadsheet are empty.

I have managed to automate the registration process with random user information and now I just need to make it do the same with the specific email and password taken from the spreadsheet.

I have tried using Apache Poi, but not exactly sure how to use it and how to make it loop itself until the end of the spreadsheet.

This what I have so far but i believe it's wrong:

val myData = new File("/desktop/files.file.xmls")

val fis = new FileInputStream(myData)

val myWorkbook = new HSSFWorkbook(fis)

val mySheet = myWorkbook.getSheetAt(0)

val rowIterator = mySheet.iterator()

while(rowIterator.hasNext){

val row = rowIterator.next()

  val cellIterator = row.cellIterator()

  while(cellIterator.hasNext) {
    val cell = cellIterator.next()
      cell.getCellType match {
        case Cell.CELL_TYPE_STRING => {
          print(cell.getStringCellValue + "\t")
        }
        case Cell.CELL_TYPE_NUMERIC => {
          print(cell.getNumericCellValue + "\t")
        }

        case Cell.CELL_TYPE_BLANK => {
          print("null" + "\t")
        }

      }
  }
  println("")
