jxl : Get total sheet data

List<List<Cell>> getSheetData(Sheet sheet){
  List<List<Cell>> data = new ArrayList<List<Cell>> ();
  int columns = sheet.getColumns();
  int rows =  sheet.getRows();

  for(int row=0; row<rows; row++){
    List<Cell> list = new ArrayList<Cell> ();
      for(int column=0; column<columns; column++){
        list.add(sheet.getCell(column, row));
      }
    data.add(list);
  }
  return data;
}

Above snippet gives you sheet data as list of rows.

You can get sample xls sheet here
