Export Html Table data to Excel in ASP.Net MVC

To export HTML table data to Excel in ASP.NET MVC, you can use a third-party library such as EPPlus or NPOI.

Here’s an example using EPPlus:

  1. Install the EPPlus library using NuGet Package Manager.
  2. In the controller, retrieve the data that you want to export to Excel and store it in a list or a data table.
  3. Create a new ExcelPackage object and add a new worksheet to it.
  4. Use a for loop to iterate through the data and add each row to the worksheet.
  5. Set the content type to “application/vnd.openxmlformats-officedocument.spreadsheetml.sheet” and the file name to “ExportedData.xlsx”.
  6. Return the ExcelPackage as a FileContentResult.

Here’s an example code to achieve the above steps:

using System.Data;
using OfficeOpenXml;

public FileContentResult ExportToExcel(List<YourModel> modelData)
{
    DataTable dt = new DataTable("Data");
    dt.Columns.AddRange(new DataColumn[3]
    {
        new DataColumn("ID", typeof(int)),
        new DataColumn("Name", typeof(string)),
        new DataColumn("Address", typeof(string))
    });

    foreach (var item in modelData)
    {
        dt.Rows.Add(item.ID, item.Name, item.Address);
    }

    using (ExcelPackage pck = new ExcelPackage())
    {
        ExcelWorksheet ws = pck.Workbook.Worksheets.Add("Data");
        ws.Cells["A1"].LoadFromDataTable(dt, true);
        return File(pck.GetAsByteArray(), "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "ExportedData.xlsx");
    }
}

Note: This example exports the data to an .xlsx file, but you can also export it to .csv or other formats.
