In this article I will explain with an example, how to export HTML Table to Excel file using jQuery in ASP.Net Core MVC.
The HTML Table will be exported (converted) to Excel file using the jQuery table2excel plugin in ASP.Net Core MVC.
 
 
Controller
The Controller consists of following Action method.
Action method for handling GET operation
Inside this Action method, simply the View is returned.
public class HomeController : Controller
{
    public IActionResult Index()
    {
        return View();
    }
}
 
 
View
The View consists of an HTML Table and a Button.
Inside the jQuery document ready event handler, the Export Button has been assigned a jQuery Click event handler.
When the Export Button is clicked, the jQuery table2excel plugin is applied to the HTML Table and it is converted (exported) to Excel file.
The jQuery table2excel plugin accepts filename parameter which sets the name of the Excel file.
