In my opinion this is the easiest and instantly working method of exporting datagridview.

 try
        {
            SaveFileDialog sfd = new SaveFileDialog();
            sfd.Filter = "Excel Documents (*.xlsx)|*.xlsx";
            sfd.FileName = "ProfitLoss.xlsx";
            if (sfd.ShowDialog() == DialogResult.OK)
            {
                DataTable dts = new DataTable();
                for (int i = 0; i < grdProfitAndLoss.Columns.Count; i++)
                {
                    dts.Columns.Add(grdProfitAndLoss.Columns[i].Name);
                }
                for (int j = 0; j < grdProfitAndLoss.Rows.Count; j++)
                {
                    DataRow toInsert = dts.NewRow();
                    int k = 0;
                    int inc = 0;
                    for (k = 0; k < grdProfitAndLoss.Columns.Count; k++)
                    {
                        if (grdProfitAndLoss.Columns[k].Visible == false) { continue; }
                        toInsert[inc] = grdProfitAndLoss.Rows[j].Cells[k].Value;
                        inc++;
                    }
                    dts.Rows.Add(toInsert);
                }
                dts.AcceptChanges();
                ExcelUtlity obj = new ExcelUtlity();
                obj.WriteDataTableToExcel(dts, "Profit And Loss", sfd.FileName, "Profit And Loss");
                MessageBox.Show("Exported Successfully");
            }
        }
        catch (Exception ex)
        {

        }
