Answer 1

You need to enclose all of that in table tags. Excel can understand HTML table structures.

Try:

Response.Write("<table>");
Response.Write(stringWrite.ToString()); 
Response.Write("</table>");

Answer 2

you should make the output file a proper html file, with the html and body tags. That should work better.

Answer 3

not to answer your question directly, but given you my opinion

for that kinda of data, is in my opinion that you should use a GridView control, taking your example you will need to write something like:

<asp:Repeater ID="rpt" runat="server" DataSourceID="ods">
    <HeaderTemplate>
        <table>
        <tr>
            <td>Header</td>
            <td>Type</td>
            <td>Name</td>
            <td>Date</td>
            <td>Amount</td>
        </tr>
    </HeaderTemplate>
    <ItemTemplate>
        <tr>
            <td>
                <%#Eval("Header")%>
            </td>
            <td>
                <%#Eval("Type")%>
            </td>
            <td>
                <%#Eval("Name")%>
            </td>
            <td>
                <%#Eval("Date", "{0:d}")%>
            </td>
            <td>
                <%#Eval("Value", "{0:c}")%>
            </td>
        </tr>
    </ItemTemplate>
    <FooterTemplate>
        </table>
    </FooterTemplate>
</asp:Repeater>

using a GridView all ou nee dto write in the HTML part is only:

<asp:GridView ID="gv" runat="server" DataSourceID="ods" AutoGenerateColumns="false">
    <Columns>
        <asp:BoundField DataField="Header" HeaderText="Header" />
        <asp:BoundField DataField="Type" HeaderText="Type" />
        <asp:BoundField DataField="Name" HeaderText="Name" />
        <asp:BoundField DataField="Date" DataFormatString="{0:d}" HeaderText="Date" />
        <asp:BoundField DataField="Value" DataFormatString="{0:c}" HeaderText="Value" />
    </Columns>
</asp:GridView>

something simpler and easier to read

you will have much more control using a GridView object rather than a Repeater, and, you will never have that kinda of problems, because rendering the gridView will always came with the table tags.

Hope it helps

And BTW, I tested your case and i did not got any problems even if I was not writting the tags like Spencer mention.

to see my code: File with HTML and Method - File with myObject
