[Extra Quality] Download Excel File Using Ajax Javascript

I have got a problem with getting excel file and opening download window in the browser after getting a response (in success ajax method) with that file. I have got appropriate Content-Type and Content-Disposition headers, I tried using Blob in js and I couldn't achieve what I want - simple file downloading.

I accomplished few versions of my ajax, one of them is below. I developed ajax which returns excel file which I couldn't open properly because it's corrupted (despite .xlsx extension).

I tried using "xhr.response" instead of "data" from success method arguments but it doesn't work too. I checked Response Headers in Developer Tools in Chrome and they are set properly.

The important thing - all the excel workbooks created on the server side is correct because it worked in the previous version when data was sent in URL, not in ajax post.

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.

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. and, having the file in the Cache, is faster to retrieve it.

This thread helped me create my own solution that I will share here. I was using a GET ajax request at first without issues but it got to a point where the request URL length was exceeded so I had to swith to a POST.

I have the following function that is pulling data from a database. The ajax call is working correctly. How can I send the tab delimited data in my success function to the user? Setting the contect type to "application/vnd.ms-excel" didn't work. The alert on success shows the correctly formatted data.

I am working on an application where I can have a grid with X items, and each item has a print button. Clicking this print button allows me to call an ajax function which passes the ID of the grid item to a controller. I retrieve the relevant data based on that ID and then download it in an excel file. (The retrieving of the specific item is not yet done)

that is pretty annoying (and unprofessional).If you're not bounded to old excel version - xls - but can use most recent file format xlsx, I'd rather use DocumentFormat.OpenXml nuget package or other packages/libraries for excel generation.Honestly, DocumentFormat.OpenXml is powerful but a little boring to use, when you have many columns and you just have a flat list of objects to report.If you are using .NET Framework (not Dotnet Core), you can try CsvHelper.Excel nuget package. Usage is pretty straight forward. Your ExportToExcel method will become something like:

I am creating an outlook plugin for one of my projects and I used the Visual Studio VB Outlook Add-In to create the predefined template. The HTML file works well but the script in HTML file has issue processing the ajax success() function. The office libraries do not let the native java script functions run (like alert statements). The data from API can be viewed in console but cannot be caught using a DIV or JSON(stringify) methods.

When I open generate_excel.php directly from the browser, the result file is downloaded.But if I make an ajax call to the generate_excel.php, I don't get the download prompt. Using chrome developer tools, I can see from the Network tab that the ajax call was successfully completed and a bunch of random characters is seen in the response data. I'm assuming that is the excel object.

Does anyone know how I can achieve the download excel feature using ajax? I don't want to refresh the page. When the user clicks on the "export" button, there should be an ajax call to the php file and prompt the user to download.

I added a hidden iframe in the page. When the ajax call returns, it returns the url of the created data. I used javascript to redirect the iframe to that url which automatically triggers the download action.

When I call above code directly from the browser, the result file is downloaded. But if I make an ajax call to above code, I don't get the download prompt. I can see from console tab that the ajax call was successfully completed and a bunch of random characters is seen in the response data. I'm assuming that is the excel object.

I create an application with NDWS using sapui5 _javascript. I have a table in the view, which has some data (data is sync with database on server). I want to retrieve data from the table and export in into excel (so get separate excel doc). Here is my trigger:

I found a fix that while it's not actually using ajax it does allow you to use a javascript call to request the download and then get a callback when the download actually starts. I found this helpful if the link runs a server side script that takes a little bit to compose the file before sending it. so you can alert them that it's processing, and then when it does finally send the file remove that processing notification. which is why I wanted to try to load the file via ajax to begin with so that I could have an event happen when the file is requested and another when it actually starts downloading.

I've performed an ajax post request to send informations through a webscript that extends the AbstractWebScript webscript type. The java controller class processes the json object and writes the response ( file excel) in the WebScriptResponse object (incomplete function).

One of the biggest concerns about this approach is managing the big amount of data in the client and whether GlideAjax can handle that amount of data or not... however I did a reasonable stress test using an excel file with just three columns (Name, Serial numbers, Class) containing ~7300 CIs rows.

Export data to Excel is very useful on the data list for nearly every web application. The export feature helps to download the data list as a file format for offline use. Excel format is ideal for exporting data in a file. Mostly the server-side method is used for export data to excel using PHP. But if you want a client-side solution to export table data to excel, it can be easily done using JavaScript.

The client-side export functionality makes the web application user-friendly. Using JavaScript, the HTML table data can be easily exported without page refresh. In this tutorial, we will show you how to export HTML table data to excel using JavaScript. The JavaScript export functionality can be used in the member list, product list, or other lists to download the data list in excel file format.

When using a request method other than "GET" Tabulator will send any parameters with a content type of form data. You can change the content type with the ajaxContentType option. This will ensure parameters are sent in the format you expect, with the correct headers.

When making an ajax request there are two different ways to detect errors with the request. In both cases if you are using the built in request promise then these callbacks will be passed the Fetch Response Object as their first argument, which allows access to the response content, status code, etc.

Ive used the plugin couple of times and has worked like charm. Currently I am using the plugin to download an excel file which would get created from the data retrieved from the database. I am using java servlets. The download is working fine but I wanted to send some specific messages back to javascript. Is there anyway I can do that from within your script? or use exiting parameters to get the data sent from the server as JSON string? Whatever I send back is getting embedded within the iframe that gets dynamically added but with a delay. There is no way I can determine whether the file was literally created or not. Do let me know if I am not very clear or missing something. 2351a5e196
