This one seems the closest to what I'm after: asp-net-mvc-downloading-excel - but I'm not sure I understand the response, and it is a couple years old now. I also came across another article can't find it anymore about using an iframe to handle the file download, but I'm not sure how to get this working with MVC. You can't directly return a file for download via an AJAX call so, an alternative approach is to to use an AJAX call to post the related data to your server. My original answer below was over 3 years old, so I thought I would update as I no longer create files on the server when downloading files via AJAX however, I have left the original answer as it may be of some use still depending on your specific requirements.

A common scenario in my MVC applications is reporting via a web page that has some user configured report parameters Date Ranges, Filters etc. When the user has specified the parameters they post them to the server, the report is generated say for example an Excel file as output and then I store the resulting file as a byte array in the TempData bucket with a unique reference.

This reference is passed back as a Json Result to my AJAX function that subsequently redirects to separate controller action to extract the data from TempData and download to the end users browser.

One other change that could easily be accommodated if required is to pass the MIME Type of the file as a third parameter so that the one Controller action could correctly serve a variety of output file formats.

This removes any need for any physical files to created and stored on the server, so no housekeeping routines required and once again this is seamless to the end user. Note, the advantage of using TempData rather than Session is that once TempData is read the data is cleared so it will be more efficient in terms of memory usage if you have a high volume of file requests.

See TempData Best Practice. Once the file has been created on the server pass back the path to the file or just the filename as the return value to your AJAX call and then set the JavaScript window. From the end users perspective, the file download operation is seamless as they never leave the page on which the request originates. My 2 cents - you don't need to store the excel as a physical file on the server - instead, store it in the Session Cache.

Use a uniquely generated name for your Cache variable that stores that excel file - this will be the return of your initial ajax call. This way you don't have to deal with file access issues, managing deleting the files when not needed, etc. Spreadsheet to generate the Excel file and it has a Save to Stream option.

That being said, there are a number of ways to create Excel files that can easily be written to a memory stream. In IE, Chrome, and Firefox, the browser prompts to download the file and no actual navigation occurs.

I used the solution posted by CSL but I would recommend you dont store the file data in Session during the whole session. By using TempData the file data is automatically removed after the next request which is the GET request for the file. You could also manage removal of the file data in Session in download action. The accepted answer didn't quite work for me as I got a Bad Gateway result from the ajax call even though everything seemed to be returning fine from the controller.

Perhaps I was hitting a limit with TempData - not sure, but I found that if I used IMemoryCache instead of TempData , it worked fine, so here is my adapted version of the code in the accepted answer:. This thread helped me create my own solution that I will share here. The javascript uses JQuery file download plugin and consists of 2 succeeding calls.

CSL's answer was implemented in a project I'm working on but the problem I incurred was scaling out on Azure broke our file downloads. I may sound quite naive, and may attract quite a criticism, but here's how I did it, It doesn't involve ajax for export, but it doesn't do a full postback either. Thanks for this post and this answer. Create a simple controller. The whole point of the trick seems that, we are posting a form a part of the Razor View upon which we are calling an Action method , which returns: a FileResult , and this FileResult returns the Excel File..
