    File inputWorkbook = new File(path);
    Workbook w;
    try{
        w = Workbook.getWorkbook(inputWorkbook);
        Sheet sheet = w.getSheet(0);
        for (int i = 1; i < sheet.getRows(); i++) {
            for (int j = 0; j < sheet.getColumns(); j++) {
                Cell cell = sheet.getCell(j, i);
                if (j == 0) {
                    String name= cell.getContents().trim();
                } 
            }
        }
    }catch(Exception ex){
        ex.printStackTrace();

import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFSheet;

try{
    FileInputStream file = new FileInputStream(new File("C:\\test.xlsx"));

    //Get the workbook instance for XLS file 
    XSSFWorkbook workbook = new XSSFWorkbook (file);

    //Get first sheet from the workbook
    XSSFSheet sheet = workbook.getSheetAt(0);

    //Get iterator to all the rows in current sheet
    Iterator<Row> rowIterator = sheet.iterator();

    //Get iterator to all cells of current row
    Iterator<Cell> cellIterator = row.cellIterator();

     while(cellIterator.hasNext()) {
            Cell cell = cellIterator.next();    
            switch(cell.getCellType()) {
                case Cell.CELL_TYPE_BOOLEAN:
                    System.out.print(cell.getBooleanCellValue() + "\t\t");
                    break;
