使用Apache POI在Excel文件中获取列的名称

Question

如何使用Apache POI在Excel文件中获取列名，以确保按预期顺序排列列。

Answer 1

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);
}

Answer 2

Or this:

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

Row indexes start from 0.

Answer 3

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();

Answer 4

要获取单元名称：

String cellName = new CellAddress(intRow, intCol).toString();
