Hello group, a question please. The data from my databases all come out in a single string per row in the .csv file, how can I print it in a cell per field in the .csv file? I attach images and code for more clarity with the problem. Thanks

public partial class CS : System.Web.UI.Page {
protected void ExportCSV(object sender, EventArgs e)
{
string constr = ConfigurationManager.ConnectionStrings["PRUEBASConnectionString"].ConnectionString;
using (SqlConnection con = new SqlConnection(constr))
{
using (SqlCommand cmd = new SqlCommand("SELECT * FROM Customers"))
{
using (SqlDataAdapter sda = new SqlDataAdapter())
{
cmd.Connection = con;
sda.SelectCommand = cmd;
using (DataTable dt = new DataTable())
{
sda.Fill(dt);

                     //Build the CSV file data as a Comma separated string.
                     string csv = string.Empty;

                     foreach (DataColumn column in dt.Columns)
                     {
                         //Add the Header row for CSV file.
                         csv += column.ColumnName + ',';
                     }

                     //Add new line.
                     csv += "\\r\\n";

                     foreach (DataRow row in dt.Rows)
                     {
                         foreach (DataColumn column in dt.Columns)
                         {
                             //Add the Data rows.
                             csv += row\[column.ColumnName\].ToString().Replace(",", ";") + ',';
                         }

                         //Add new line.
                         csv += "\\r\\n";
                     }

                     //Download the CSV file.
                     Response.Clear();
                     Response.Buffer = true;
                     Response.AddHeader("content-disposition", "attachment;filename=SqlExport.csv");
                     Response.Charset = "";
                     Response.ContentType = "application/text";
                     Response.Output.Write(csv);
                     Response.Flush();
                     Response.End();
                 }
             }
         }
     }
 } }
