好吧，如果您的问题标记为 Delphi 7，我假设您有 BDE。这将使您能够在 Delphi 中完成整个过程。

您可以修改并使用这个未经测试的代码（您将需要添加异常处理）：

procedure TForm1.Button2Click(Sender: TObject);
var
  Cols: integer;
  Rows: integer;
  IntCellValue: integer;
  Excel, XLSheet: Variant;
  failure: Integer;

begin
  failure:=0;
  try
    Excel:=CreateOleObject('Excel.Application');
  except
    failure:=1;
  end;
  if failure = 0 then
  begin
    Excel.Visible:=False;
    Excel.WorkBooks.Open(<Excell_Filename>);
    XLSheet := Excel.Worksheets[1];
    Cols := XLSheet.UsedRange.Columns.Count;
    Rows := XLSheet.UsedRange.Rows.Count;

    // Value of the 1st Cell
    IntCellValue:=Excel.Cells[1, 1].Value;
    // Iterate Cals/Rows to read the data section in your worksheet
    // and you can write it in Paradox using the BDE by iterating all cells
    // somthing like this pseudo code:

      try            
        Query := TQuery.Create(nil)            
        Query .Databasename := PdxDBName; // must be configured in the BDE
        while Rows > 0
        begin
          while Cols > 0
          begin
            IntCellValue:=Excel.Cells[Cols,Rows].Value;
            Query .SQL.text := // SQLStmt including the IntCellValue
            ExecSQL;
            dec(Cols);               
          end;
          Cols := XLSheet.UsedRange.Columns.Count;
        Dec(Rows);
        end;
      finally
        Query.Free;
      end;

    Excel.Workbooks.Close;
    Excel.Quit;
    Excel:=Unassigned;
  end;
end;

Well, if you have the question tagged as Delphi 7 I assume you have BDE. This will enable you to do the whole process in Delphi.

You can modify and use this untested code (you will need to add the exception handling):

procedure TForm1.Button2Click(Sender: TObject);
var
  Cols: integer;
  Rows: integer;
  IntCellValue: integer;
  Excel, XLSheet: Variant;
  failure: Integer;

begin
  failure:=0;
  try
    Excel:=CreateOleObject('Excel.Application');
  except
    failure:=1;
  end;
  if failure = 0 then
  begin
    Excel.Visible:=False;
    Excel.WorkBooks.Open(<Excell_Filename>);
    XLSheet := Excel.Worksheets[1];
    Cols := XLSheet.UsedRange.Columns.Count;
    Rows := XLSheet.UsedRange.Rows.Count;

    // Value of the 1st Cell
    IntCellValue:=Excel.Cells[1, 1].Value;
    // Iterate Cals/Rows to read the data section in your worksheet
    // and you can write it in Paradox using the BDE by iterating all cells
    // somthing like this pseudo code:

      try            
        Query := TQuery.Create(nil)            
        Query .Databasename := PdxDBName; // must be configured in the BDE
        while Rows > 0
        begin
          while Cols > 0
          begin
            IntCellValue:=Excel.Cells[Cols,Rows].Value;
            Query .SQL.text := // SQLStmt including the IntCellValue
            ExecSQL;
            dec(Cols);               
          end;
          Cols := XLSheet.UsedRange.Columns.Count;
        Dec(Rows);
        end;
      finally
        Query.Free;
      end;

    Excel.Workbooks.Close;
    Excel.Quit;
    Excel:=Unassigned;
  end;
end;
