第一种方法delphi 快速导出excel
uses ComObj,clipbrd; function ToExcel(sfilename:string; ADOQuery:TADOQuery):boolean; const xlNormal=-4143; var y : integer; tsList : TStringList; s,filename :string; aSheet :Variant; excel :OleVariant; savedialog :tsavedialog; begin Result := true; try excel:=CreateOleObject(\'Excel.Application\'); excel.workbooks.add; except //screen.cursor:=crDefault; showmessage(\'无法调用Excel！\'); exit; end; savedialog:=tsavedialog.Create(nil); savedialog.FileName:=sfilename; //存入文件 savedialog.Filter:=\'Excel文件(*.xls)|*.xls\'; if savedialog.Execute then begin if FileExists(savedialog.FileName) then try if application.messagebox(\'该文件已经存在，要覆盖吗？\',\'询问\',mb_yesno+mb_iconquestion)=idyes then DeleteFile(PChar(savedialog.FileName)) else begin Excel.Quit; savedialog.free; //screen.cursor:=crDefault; Exit; end; except Excel.Quit; savedialog.free; screen.cursor:=crDefault; Exit; end; filename:=savedialog.FileName; end; savedialog.free; if filename=\'\' then begin result:=true; Excel.Quit; //screen.cursor:=crDefault; exit; end; aSheet:=excel.Worksheets.Item[1]; tsList:=TStringList.Create; //tsList.Add(\'查询结果\'); //加入标题 s:=\'\'; //加入字段名 for y := 0 to adoquery.fieldCount - 1 do begin s:=s+adoQuery.Fields.Fields[y].FieldName+#9 ; Application.ProcessMessages; end; tsList.Add(s); try try ADOQuery.First; While Not ADOQuery.Eof do begin s:=\'\'; for y:=0 to ADOQuery.FieldCount-1 do begin s:=s+ADOQuery.Fields[y].AsString+#9; Application.ProcessMessages; end; tsList.Add(s); ADOQuery.next; end; Clipboard.AsText:=tsList.Text; except result:=false; end; finally tsList.Free; end; aSheet.Paste; MessageBox(Application.Handle,\'数据导出完毕！\',\'系统提示\',MB_ICONINFORMATION or MB_OK); try if copy(FileName,length(FileName)-3,4)<>\'.xls\' then FileName:=FileName+\'.xls\'; Excel.ActiveWorkbook.SaveAs(FileName, xlNormal, \'\', \'\', False, False); except Excel.Quit; screen.cursor:=crDefault; exit; end; Excel.Visible := false; //true会自动打开已经保存的excel Excel.Quit; Excel := UnAssigned; end;
调用: ToExcel(\'D:\a.xsl\',QueryToExcel);//路径可以自定义

delphi导出数据至Excel的三种方法及比较闲来无事，跑到网上搜集了几种导出DataSet至Excel的几种方法。另外使用GetTickcount函数计算时差，以便比较。（本来使用Timer控件，但是Timer不适合做高精度时间计算）使用TADOConnect，TADOQuery查询数据。方法五： 使用TADOQuery + Varaint方法，循环遍历数据集中数据，直接插入到Excel的WookBook单元。这是初学者最易懂和易接受的方法。在下面代码中没有仔细注意语法（比如没有使用try..finally结构体），如果需要使用，请注意：//使用ADO循环方式保存。
procedure TForm1.btn_WhileClick(Sender: TObject); var Eclapp:variant; n:integer; filename: string; t1,t2: Int64; begin Eclapp := CreateOleObject(\'Excel.Application\'); Eclapp.WorkBooks.Add; Eclapp.Visible:= False; filename :=\'d:\数据1.xls\'; lbl2.Caption := \'0\'; if FileExists(fileName) then DeleteFile(fileName); t1:= GetTickCount; qry1.DisableControls; qry1.First; n:=2; while not qry1.Eof do begin eclapp.cells[n,1] := qry1.Fields[0].AsString; eclapp.cells[n,2] := qry1.Fields[1].AsString; eclapp.cells[n,3] := qry1.Fields[2].AsString; eclapp.cells[n,4] := qry1.Fields[3].AsString; //为了简单，只添加了4个栏位 inc(n); qry1.Next; application.ProcessMessages; end; qry1.EnableControls; t2:= GetTickCount; eclapp.visible := false; eclapp.Workbooks[1].SaveAs(filename); Eclapp.Quit; Eclapp:= Unassigned; lbl2.Caption := IntToStr(t2 - t1); end;
方法六：使用OLE方法导入。 先讲TDateSet中的数据保存为二维OLEVariant数组中，再保存到Excel Sheet中 ///使用OLE方式保存。
procedure TForm1.btn_OleVariantClick(Sender: TObject); var fileName: string; xlApp, Sheet: OleVariant; rowCount, Colcount, index: Integer; t1,t2: Int64; function RefToCell(RowID, ColID: Integer): string; var ACount, APos: Integer; begin ACount := ColID div 26; APos := ColID mod 26; if APos = 0 then begin ACount := ACount - 1; APos := 26; end; if ACount = 0 then Result := Chr(Ord(
