Export to excel from model instead of controller

I'm using the following to export to excel in an MVC application from a Controller. To do this I have to use some business logic and data objects in the Controller. My export works, but I don't think I should do this in the Controller. I'm new to MVC. Is there a better way to move this logic to the Model and get it out of the Controller?

public void ExportToExcel(PortalAccountMappingModel model)

    {
        var data = model.GetExport();
        var excelReport = new ExcelReportGenerator(Configurations.ReportTemplatesFolder);
        using (ExcelReportData reportData = excelReport.GenerateReport(ExcelReportDataOutputType.StreamData, Constants.PORTAL_ACCOUNT_MAPPING_REPORT_NAME, typeof(PortalAccountMappingReportItem), data))
        {
            byte[] reportByteArray = reportData.DataStream.ToArray();
            Response.Clear();
            Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}", reportData.FileName));
            Response.AddHeader("Content-Length", reportByteArray.Length.ToString());
            Response.ContentType = "application/octet-stream";
            Response.BinaryWrite(reportByteArray);
        }
    }
