很多时候我们需要把表格形式的数据转换成EXECL的形式呈现在用户面前，其中有好几个方法可以做到一点，我将介绍一种利用ASP完成的方法，该方法允许服务器动态地创建EXECL报表而且不用占用任何服务器空间。该方法还允许多个用户同时收到该数据。但是该方法至少需要EXECL 97的支持。
废话少说，要完成这个工作最重要的是要告诉浏览器HTTP头，就用如下代码：
<%
Response.ContentType = "application/vnd.ms-excel"
%>
下面来看一个例子，假设现在有如下形式的数据：
flavor qty_baked qty_eaten qty_sold price
Boston 24 2 10 0.5
Jelly 24 1 12 0.5
Strawberry 36 1 15 0.5
Chocolate 24 2 6 0.75
Maple 12 1 6 0.75
客户要求用EXECL的形式表现出来，并且希望其中能加上其他一些计算汇总
用如下代码：
……
<%
Response.ContentType = "application/vnd.ms-excel"
set conntemp=server.createobject("adodb.connection")
cnpath="DBQ=" & server.mappath("/stevesmith/data/timesheet.mdb")
conntemp.Open "DRIVER={Microsoft Access Driver (*.mdb)}; " & cnpath
set RS=conntemp.execute("select * from donut")
%>
<TABLE BORDER=1>
<TR>
<%
' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
' % Loop through Fields Names and print out the Field Names
' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
j = 2 'row counter
For i = 0 to RS.Fields.Count - 1
%>
<TD><B><% = RS(i).Name %></B></TD>
<% Next %>
<TD><B>On Hand (calculated)</B></TD>
<TD><B>Gross (calculated)</B></TD>
</TR>
<%
' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
' % Loop through rows, displaying each field
' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Do While Not RS.EOF
%>
<TR>
<% For i = 0 to RS.Fields.Count - 1
%>
<TD VALIGN=TOP><% = RS(i) %></TD>
<% Next %>
<TD>=b<%=j%>-c<%=j%>-d<%=j%></TD>
<TD>=d<%=j%>*e<%=j%></TD>
</TR>
<%
RS.MoveNext
j = j + 1
Loop
' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
' % Make sure to close the Result Set and the Connection object
' %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
RS.Close
%>
<TR BGCOLOR=RED>
<TD>Totals</TD>
<TD>=SUM(B2:B6)</TD>
<TD>=SUM(C2:C6)</TD>
<TD>=SUM(D2:D6)</TD>
<TD>n/a</TD>
<TD>=SUM(F2:F6)</TD>
<TD>=SUM(G2:G6)</TD>
</TABLE>
……
这样我们就实现了目的，用户可以在浏览器窗口就打开它进行简单操作，也可以保存到硬盘上进行其他操作。我还将介绍一种利用filesystemobject操作的方法。请稍候。：）
