excel - 将数据从 DBGrid 导出到 Excel

Question

我想知道是否有人有办法将数据从 DBGrid 导出到 Excel？我正在使用 Delphi 7 、 Excel 2007 和 ADO 。
任何帮助将不胜感激。

如果您想快速导出原始数据，只需使用类似的内容导出记录集(ADODataset.recordset)即可:

procedure ExportRecordsetToMSExcel(DestName: string; Data: _Recordset);
var
  ovExcelApp: OleVariant;
  ovExcelWorkbook: OleVariant;
  ovWS: OleVariant;
  ovRange: OleVariant;
begin
  ovExcelApp := CreateOleObject('Excel.Application'); //If Excel isnt installed will raise an exception
  try
    ovExcelWorkbook   := ovExcelApp.WorkBooks.Add;
    ovWS := ovExcelWorkbook.Worksheets.Item[1]; // go to first worksheet
    ovWS.Activate;
    ovWS.Select;
    ovRange := ovWS.Range['A1', 'A1']; //go to first cell
    ovRange.Resize[Data.RecordCount, Data.Fields.Count];
    ovRange.CopyFromRecordset(Data, Data.RecordCount, Data.Fields.Count); //this copy the entire recordset to the selected range in excel
    ovWS.SaveAs(DestName, 1, '', '', False, False);
  finally
    ovExcelWorkbook.Close(SaveChanges := False);
    ovWS := Unassigned;
    ovExcelWorkbook := Unassigned;
    ovExcelApp := Unassigned;
  end;
end;
