Get columns' names in Excel file using Apache POI

问题

How to get the column names in an Excel file using Apache POI, to make sure that the columns are ordered as expected.

回答1:

Or this:

cell.getSheet().getRow(0).getCell(currentcellIndex)
    .getRichStringCellValue().toString()

Row indexes start from 0.

回答2:

There is a convenience method for this:

CellReference.convertNumToColString(cell.getColumnIndex());

To get the full name:

private static String getCellName(Cell cell)
{
    return CellReference.convertNumToColString(cell.getColumnIndex()) + (cell.getRowIndex() + 1);
}

Apache POI, translating Excel column number to letter

      FileInputStream fis = new FileInputStream(
      new File("D:\\workspace\\Writesheet.xlsx"));
      @SuppressWarnings("resource")
      XSSFWorkbook workbook = new XSSFWorkbook(fis);
      XSSFSheet spreadsheet = workbook.getSheetAt(0);

      int lastcell=spreadsheet.getRow(0).getLastCellNum();
      //Non empty Last cell Number or index return

      for(int i=0;i<=lastcell;i++)
      {
          try
          {
              System.out.println(CellReference.convertNumToColString(i));
          }catch(Exception e)
          {}
      }
      fis.close();
