To export data to Excel, you can use the ClosedXML.Report library (https://github.com/ClosedXML/ClosedXML.Report). Believe me, this is a wonderful library and easy for her to use. The library does not need Excel Interop. ClosedXML.Report generates an Excel file based on a template that you can create in Excel using any formatting. For example:

    var template = new XLTemplate(@".\Templates\report.xlsx");

    using (var db = new DbDemos())
    {
        var cust = db.customers.LoadWith(c => c.Orders).First();
        template.AddVariable(cust);
        template.Generate();
    }

    template.SaveAs(outputFile);
