            string[] lines = File.ReadAllLines("Distances.xlsx");
            foreach (string line in lines)
            {
                Console.WriteLine(line);
            }

            string[] lines = File.ReadAllLines("Distances.xlsx");
            foreach (string line in lines)
            {
                Console.WriteLine(line);
            }

But it only return of bunch of random symbol, do u know how I shloud procede to read my file?

thx, closedxml worked, I did this :

            string cheminFichier = "filepath";

            using (var classeur = new XLWorkbook(cheminFichier))
            {
                var feuille = classeur.Worksheet(1);

                foreach (var cellule in feuille.CellsUsed())
                {
                    Console.WriteLine($"Cellule {cellule.Address}: {cellule.Value}");
                }
            }

            string cheminFichier = "filepath";

            using (var classeur = new XLWorkbook(cheminFichier))
            {
                var feuille = classeur.Worksheet(1);

                foreach (var cellule in feuille.CellsUsed())
                {
                    Console.WriteLine($"Cellule {cellule.Address}: {cellule.Value}");
                }
            }

And it worked well how do I mark that this problem is solved?
