how to create a excel/csv file on the fly?

Hello, I did my search around here and find Shooksm's code.

<cfheader name="content-disposition" value="attachment;filename=#Left(CreateUUID(), 8)#.html">
<cfcontent type="application/octet-stream">
<html>
     <head>
     <title>Your Custom Query</title>
</head>
<body>
<cfoutput>
<table border="1" width="100%"><cfloop index="i" from="0" to="95" step="5">
     <tr>
          <td>#i+1#</td>
          <td>#i+2#</td>
          <td>#i+3#</td>
          <td>#i+4#</td>
          <td>#i+5#</td>
     </tr></cfloop>
</table>
</cfoutput>
</body>
</html>


But after I copied and pasted into a blank cfm file, when I call it from browser. it returns the table in the browser though I was expecting a download box pop up?

I am using CF4.5 by the way, could that be the reason?

Also it seems the <cfsavecontent> is introduced in 5.0. What should I do to get the equvilent?

I am trying to develop a page to show a table report and if clients want, they can click a button/link to download it into excel. I hope there is a way I don't need to write the report twice.

Thanks,
lyrix

Try this :

<cfcontent type="application/msexcel">

instead of octet-stream

Great! It works!

Do you happen to know the answer to the other question? How do I use something else in 4.5 for <cfsavecontent> so I don't need to write twice or the server won't need to run twice for the online report and downloadable report?

Thanks,
lyrix

Unfortunately I am not familiar with CF 4.5 so I am not sure what would work in place of <cfsavecontent>

On 4.5, I would suggest you break out the portion of your code into three files.  The first file is the one that builds the table.  The second file is used to display the report to the browser and the third is the file used to download to excel.

ReportTable.cfm would contain the following:

<cfoutput>
<table border="1" width="100%"><cfloop index="i" from="0" to="95" step="5">
     <tr>
          <td>#i+1#</td>
          <td>#i+2#</td>
          <td>#i+3#</td>
          <td>#i+4#</td>
          <td>#i+5#</td>
     </tr></cfloop>
</table>
</cfoutput>

ShowReport.cfm would look like this:

<html>
     <head>
          <title>Your Custom Query</title>
     </head>
<body>
<h3>You custom sites template stuff starts here</h3>
<cfinclude template="ReportTable.cfm">
<p><a href="DownloadReport.cfm">Download to excel</a></p>
<h4>custom site template ends here</h3>
</body>
</html>

Then in your DownloadReport:

<cfheader name="content-disposition" value="attachment;filename=#Left(CreateUUID(), 8)#.xls">
<cfcontent type="application/msexcel">
<html>
     <head>
          <title>Your Custom Query</title>
     </head>
<body>
<cfinclude template="ReportTable.cfm">
</body>
</html>

This will allow your to write your report once but show is as html or download it as excel.  Hope this helps

Hi, Shooksm, thanks for your kind help. I don't know how to split the points otherwise I must give  you some. Even though I just figure out a way around it, your method is also cool.
