hi all..<BR><BR>i use the Response.ContentType = "application/vnd.ms-excel" directive to do excel output for some reports. The problem is that we have Office XP on the server and this above mentioned directive generates excel XP output. The problem is that if the client doesn’t have Office XP installed, then they cannot read the content we are offering them. our clients have office 2000. Is there a way to do some on-the-fly conversion, by checking the client&#039;s version of office installation?<BR><BR>are there any components that help in converting an excel XP document to an excel 2000 document?<BR><BR>thanks
