Format cell size in . csv files

Question

Gero esse csv

public ActionResult geraExcel()
        {
            List<vwFinancingReportViewModel> lista = new List<vwFinancingReportViewModel>();
            lista = dadosPlanilha();

            StringBuilder sb = new StringBuilder();
            sb.Append("Status;Nro.Pessoal;Nome Completo;Grade;Nro.Solicitação;Data Financiamento;" + 
                "Ano Fabric.;Modelo;Chassi;Valor Bem;Valor Financiado;Status Solicitação;Status Pagamento;" +
                "Valor Parcela;Juros;ReembolsoKM;Reembolso Depreciação;Sequencia;Data Pagamento\r\n");
            foreach(var item in lista)
            {
                sb.Append(item.valuepayment.ToString() + ";" + item.chassi.ToString() + ";" + item.solicitationid.ToString() + "\r\n");

            }
            //sb.Append("Eduardo;11111\r\n");
            //sb.Append("Coutinho;22222\r\n");

            HttpContext.Response.Clear();
            HttpContext.Response.AddHeader("content-disposition", string.Format("attachment;filename=" + DateTime.Now.ToString("yyyyMMdd") + "ReportFinanciamentoRH.csv"));

            HttpContext.Response.ContentType = "application/CSV";
            HttpContext.Response.ContentEncoding = System.Text.Encoding.Default;

            HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);

            HttpContext.Response.Write(sb.ToString());

            HttpContext.Response.End();

            return null;
        }

I can increase the size of the cell, so that when opening the file via excel, the name (header) of the columns can appear correctly, without the need to enlarge the cell?
