在VB中使用这个。2005年净额:

Private Function ColumnName(ByVal ColumnIndex As Integer) As String

   Dim Name As String = ""

   Name = (New Microsoft.Office.Interop.Owc11.Spreadsheet).Columns.Item(ColumnIndex).Address(False, False, Microsoft.Office.Interop.Owc11.XlReferenceStyle.xlA1)
   Name = Split(Name, ":")(0)

   Return Name

End Function

在查看了这里提供的所有版本后，我决定自己使用递归来做一个。

这是我的vb.net版本:

Function CL(ByVal x As Integer) As String
    If x >= 1 And x <= 26 Then
        CL = Chr(x + 64)
    Else
        CL = CL((x - x Mod 26) / 26) & Chr((x Mod 26) + 1 + 64)
    End If
End Function

如果有人需要在没有VBA的Excel中做到这一点，这里有一种方法:

=SUBSTITUTE(ADDRESS(1;colNum;4);"1";"")

其中colNum是列号

在VBA中:

Function GetColumnName(colNum As Integer) As String
    Dim d As Integer
    Dim m As Integer
    Dim name As String
    d = colNum
    name = ""
    Do While (d > 0)
        m = (d - 1) Mod 26
        name = Chr(65 + m) + name
        d = Int((d - m) / 26)
    Loop
    GetColumnName = name
End Function

似乎很多答案都比必要的要复杂得多。下面是一个基于上面描述的递归的通用Ruby答案:

这个答案的一个好处是，它不局限于26个英文字母。你可以在COLUMNS常量中定义任何你喜欢的范围，它会做正确的事情。

  # vim: ft=ruby
  class Numeric
    COLUMNS = ('A'..'Z').to_a

    def to_excel_column(n = self)
      n < 1 ?  '' : begin
        base = COLUMNS.size
        to_excel_column((n - 1) / base) + COLUMNS[(n - 1) % base]
      end
    end
  end

  # verify:
  (1..52).each { |i| printf "%4d => %4s\n", i, i.to_excel_column }

这将打印以下内容，例如:

   1 =>    A
   2 =>    B
   3 =>    C
  ....
  33 =>   AG
  34 =>   AH
  35 =>   AI
  36 =>   AJ
  37 =>   AK
  38 =>   AL
  39 =>   AM
  40 =>   AN
  41 =>   AO
  42 =>   AP
  43 =>   AQ
  44 =>   AR
  45 =>   AS
  46 =>   AT
  47 =>   AU
  48 =>   AV
  49 =>   AW
  50 =>   AX
  51 =>   AY
  52 =>   AZ

精炼原始的解决方案(在c#中):

public static class ExcelHelper
{
    private static Dictionary<UInt16, String> l_DictionaryOfColumns;

    public static ExcelHelper() {
        l_DictionaryOfColumns = new Dictionary<ushort, string>(256);
    }

    public static String GetExcelColumnName(UInt16 l_Column)
    {
        UInt16 l_ColumnCopy = l_Column;
        String l_Chars = "0ABCDEFGHIJKLMNOPQRSTUVWXYZ";
        String l_rVal = "";
        UInt16 l_Char;


        if (l_DictionaryOfColumns.ContainsKey(l_Column) == true)
        {
            l_rVal = l_DictionaryOfColumns[l_Column];
        }
        else
        {
            while (l_ColumnCopy > 26)
            {
                l_Char = l_ColumnCopy % 26;
                if (l_Char == 0)
                    l_Char = 26;

                l_ColumnCopy = (l_ColumnCopy - l_Char) / 26;
                l_rVal = l_Chars[l_Char] + l_rVal;
            }
            if (l_ColumnCopy != 0)
                l_rVal = l_Chars[l_ColumnCopy] + l_rVal;

            l_DictionaryOfColumns.ContainsKey(l_Column) = l_rVal;
        }

        return l_rVal;
    }
}

另一种VBA方式

Public Function GetColumnName(TargetCell As Range) As String
    GetColumnName = Split(CStr(TargetCell.Cells(1, 1).Address), "$")(1)
End Function
