Hi rani,

Database

For this example I have used of Northwind database that you can download using the link given below.

Download Northwind Database

Model

public class Customer
{
    public string CustomerID { get; set; }
    public string ContactName { get; set; }
    public string City { get; set; }
    public string Country { get; set; }
}

Controller

public class HomeController : Controller
{
    private DBCtx Context { get; }
    public HomeController(DBCtx _context)
    {
        this.Context = _context;
    }

    public IActionResult Index()
    {
        return View(this.Context.Customers.Take(10).ToList());
    }

    [HttpPost]
    public IActionResult Export(string GridHtml)
    {
        return File(System.Text.Encoding.ASCII.GetBytes(GridHtml), "application/vnd.ms-excel", "Grid.xls");
    }
}

View

@addTagHelper*, Microsoft.AspNetCore.Mvc.TagHelpers
@using Export_Table_Excel_Core_MVC.Models
@model IEnumerable<Customer>

@{
    Layout = null;
}
