Hello, here is my solution to export data to Excel with a .NET Excel library

//Connect DataBase and Export Data to DataTable
            OleDbConnection conn = new OleDbConnection();
            conn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=..\..\data\demo.mdb";
            conn.Open();
            OleDbCommand command = new OleDbCommand();
            command.CommandText
                = " select Name, Capital, Continent, Area, Population, from country ";
            command.Connection = conn;
            OleDbDataAdapter adapter = new OleDbDataAdapter(command);
            DataTable dataTable = new DataTable();
            adapter.Fill(dataTable);

            //Create Excel
            Workbook book = new Workbook();
            Worksheet sheet = book.Worksheets[0];

            //Export Data from DataTable to Excel
            sheet.InsertDataTable(dataTable, true, 1, 1);
