public static void main(String[] args) {
         String path = "C:\\testData.xlsx";
         File excelFile = new File (path);
         FileInputStream fis = null;
         try {
                fis = new FileInputStream(excelFile);
         } catch (FileNotFoundException e) {
                e.printStackTrace();
         }
         //we create an XSSF Workbook object for our XLSX Excel File
         XSSFWorkbook workbook = null;
         try {
                workbook = new XSSFWorkbook(fis);
         } catch (IOException e) {

                e.printStackTrace();
         }
         //We get first sheet
         XSSFSheet sheet = workbook.getSheetAt(0);   
         int totalColumns = sheet.getRow(0).getPhysicalNumberOfCells();

         System.out.println("Total number of Columns :::"+totalColumns);
