I have also included empty HTML div to create table inside it from our Excel file. Let's beging by adding simple HTML file input and button to upload file When file is uploaded using Javascript, it is read as Binary string initially, and then binary data is read using xlsx plugin. To check the solution just click on the link and it will download csv file which contains comma separated values as we defined.In the previous post, I have explained how we can read csv file using javascript and HTML 5 filereader, now in this post, I have explained h ow we can use external library like xlsx to parse or read excel file using javascript and show it's contents in HTML table. private string GenerateCSVString () įinally we have the working application…. In the controller implement the GenerateCSVString method to create the csv file. Now the methods and calling parts are done and we have to implement the data reading and file generating part. Otherwise the jquery will give you some errors. Make sure to register it after the jquery registration.

Then the scripts inside the custom js file will be loaded automatically into browser. Please refer to this article to learn how to add custom scripts to a project.Īnd also you have to render the script into the page layout(“_Layout.cshtml”) as in the following screen. When you add a new js file to your project, you have to register the file in the bundle config file. In this script we are reading the url from the link and call the controller method using Ajax. I have added a new Javascript file to my project and added the javascript code to call the action method in controller. If you have some special characters or unicode characters in data you have to use this kind of UTF encoding. And for the data encoding I used the UTF8Encoding. For the file name I have added the time stamp so we can see the time which we downloaded the file. This method will extract the necessary data from your database and return the created csv file. So we are promised to return a file from this method. Its a HttpGet method and the return type is FileContentResult. Now in the Home controller I added a new action method for file download. We can also use the href attribute instead of a data attribute. Please note that I have added a css class to the link and also added an action method as a data attribute though we haven’t implemented that method yet. Next added a Link to download the csv file in View. Here I’m using the default layout as the layout for this page. Then add the new view with the same name as the action. You can Right-click on the Downloads method and just click on the Add new View. Then added a new view for the new Action.

For this I have created a new ASP.NET MVC project and added a new Action (“Downloads”) to the home controller to display the downloads page.
