Hi,<BR><BR>Currently I&#039;m working on a web server which don&#039;t have(can&#039;t install) Microsoft Office. <BR><BR>But I have to export a datagrid info (eg: from dataset/reader) to excel file. First I create a txt file and then rename it as .xls file. But the problem is I can&#039;t import back the excel file back to database. It is because my excel file is not in hex/binary format. Error Message: External table is not in the expected format. So what should I do to export a excel file in correct format?<BR><BR>Second concern is to import a excel file, I will have to set the connect string. (eg: Dim strExcelConn As String = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=c:TempExcelFile\" & strFileNameOnly & ";" & _<BR> "Extended Properties=Excel 8.0;")<BR><BR>But if I dont have Microsoft Office, then the Excel 8.0 won&#039;t be found, right? <BR><BR>So what should I do to manage the import and export without installing Microsoft Office? Help....<BR>Thanks
