Ex. The procedure returned this data to me:

Now I would need to store this data somewhere and give a UPDATE in a spreadsheet already created that will be fixed in a certain way.

Here is an example code to update an Excel worksheet with C # and ADO:

var connectionStringBuilder = new 
System.Data.OleDb.OleDbConnectionStringBuilder();
connectionStringBuilder.DataSource = @"c:\dev\tmp\consolidated.xlsx";
connectionStringBuilder.Provider = "Microsoft.ACE.OLEDB.12.0";
connectionStringBuilder.Add("Extended Properties", "Excel 12.0;");

using (var connection = new System.Data.OleDb.OleDbConnection(connectionStringBuilder.ToString()))
{
    connection.Open();
    var updateCommand = connection.CreateCommand();
    updateCommand.CommandText = "update [second$] S inner join [first$] F on S.ID = F.ID set S.Language = F.Language";
    updateCommand.ExecuteNonQuery();
}
