Hi all,
I often need to export to MS Excel or other external applications some data from local dataset for little calculation or printing needings.
Is there an easy or a general way exporting local data avoiding a pass back to server?
Thanks in advance

Bill

I have written my own server - so hopefully this approach can work for you.

I get the request and build the response......  I built the CSV file as lines in a TStringList - then returned the TEXT


// set your headers....

           Response.ContentType := 'text/plain';
           Response.HeaderText :=
               Response.HeaderText +
               RtcString('Access-Control-Allow-Origin: *' + #13#10) +
               RtcString('Cache-Control: must-revalidate, post-check=0, pre-check=0' + #13#10) +
               RtcString('Cache-Control: public' + #13#10) +
               RtcString('Content-Description: File Transfer' + #13#10) +
               RtcString('Content-Disposition: attachment; filename=SageINV.csv' + #13#10);    


// this is the content                  
       Write(RtcString(Conn.EWBSAGE(Request.Query)));    // EWBSAGE Routine below creates CSV
         



function TdmUniSQL.EWBSAGE(Query: TRtcHttpValues): string;
var
 i   : integer;
 fDT : TDateTime;
 sl  : TStringList;
 sTax: string;
begin
 for i := 0 to Query.ItemCount - 1 do
 begin
   if Uppercase(Query.ItemName[i]) = 'SFROMDT' then
//      fDT := StrToDateTime(Query.ItemValue[i], fmtset);
     fDT := myStr2DT(Query.ItemValue[i]);   
 end;       

 sl := TStringList.Create;
 sl.Add('<Version>');
 sl.Add('"12001","1"');      // 1 Canada, 2 USA, 3 French, 7 International
 sl.Add('</Version>');
