Program.cs

using System;
using System.Reflection;

namespace CustomPropertyAttributes
{
    class Program
    {
        static void Main(string[] args)
        {
            var properties = typeof(ClientsExcelReport).GetProperties();
            foreach(var prop in properties)
            {
                Console.WriteLine($"Prop name: {prop.Name}");
                if(Attribute.IsDefined(prop, typeof(ExcelColumnNameAttribute)))
                    Console.WriteLine(prop.GetCustomAttribute<ExcelColumnNameAttribute>().ColumnName);
                if (Attribute.IsDefined(prop, typeof(ExcelColumnCommentAttribute)))
                    Console.WriteLine(prop.GetCustomAttribute<ExcelColumnCommentAttribute>().Comment);
                Console.WriteLine("**************");
            }
        }
    }

    class ClientsExcelReport
    {
        [ExcelColumnName("Nombre del cliente")]
        [ExcelColumnComment("Algun comentario tonto sobre la columna")]
        public string ClientName { get; set; }
        [ExcelColumnName("País")]
        public string ClientCountry { get; set; }
        [ExcelColumnName("Edad")]
        public string Age { get; set; }
        public string Status { get; set; }
    }


    public class ExcelColumnNameAttribute : Attribute
    {
        public ExcelColumnNameAttribute(string columnName)
        {
            ColumnName = columnName;
        }

        public string ColumnName { get; }
    }

    public class ExcelColumnCommentAttribute : Attribute
    {
        public ExcelColumnCommentAttribute(string comment)
        {
            Comment = comment;
        }

        public string Comment { get; }
    }
