How do I get csv file to download on IE? Works on firefox

Question

I\'m struggling with an odd error. I have a simple web app that grabs stuff from a DB then outputs it as a downloadable csv file. It works on firefox and chrome, but IE fail

Answer 1

I've had success with the following:

header("Content-type: application/vnd.ms-excel");
header("Content-disposition: attachment; filename=File.csv");

Setting the type to application/vnd.ms-excel seemed to do the trick in my case. This is all in a file that is opened by submitting a form using

target="_blank"

Answer 2

Try setting your content type to text/csv instead of application/octet-stream.

Since application/octet-stream is a generic binary mime type (and doesn't match the '.csv' extension), Internet explorer might be ignoring it and computing the mime type based on the file extension.

Answer 3

Did you try the Content-type: text/csv ?

Answer 4

If you are trying to accomplish this task (getting a CSV file to download in IE8) using Salesforce.com (in which case your front-end is Visualforce and you can't set all of the headers, only some of them), here's what you need:

<apex:page cache="true" 
        contentType="application/octet-stream#myAwesomeFileName.csv" 
        showHeader="false" sidebar="false" standardStylesheets="false">
     <apex:outputText value="{!csvContent}" escape="false"/>
</apex:page>

The key pieces here are cache=true, which, in conjunction with the default expires=0 attribute, achieves the following headers:

header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");

And then the contentType of application/octet-stream --- doing text/csv fails for IE8.

Answer 5

After using Javascript it will solve your problem.

Use this for IE,

    var IEwindow = window.open();
    IEwindow.document.write('sep=,\r\n' + CSV);
    IEwindow.document.close();
    IEwindow.document.execCommand('SaveAs', true, fileName + ".csv");
    IEwindow.close();

For more information i have written tutorial on that, see - Download JSON data in CSV format Cross Browser Support

Hope this will be helpful for you.

This simply doesn't make sense. I tried the accepted answer, all the other answers in here, and it didn't work for me. I tried their permutations, and somehow I managed to make it work in IE like so:

 header("Pragma: public");
 header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
 header("Cache-Control: public");
 header("Content-Type: application/vnd.ms-exce");
 header("Content-Disposition: attachment; filename=coupons.csv" );
 header("Content-Transfer-Encoding: binary");       
 header("Content-Length: " . strlen($csv)); 
 echo $csv;
 die();

One thing I did is to empty the cache every freaking time I test the code. And it still doesn't make sense. Just in case someone might need this desperately ;)
