Import fichier .csv dans Excel ?...

Bonjour

Je n'arrive pas à importer et ouvrir correctement dans excel un fichier .CSV

J'ai essayé de l'ouvrir également après l'avoir transformé en fichier "texte" dans word, mais excel ne reconnait pas les séparateurs et affiche toutes les données dans une seule colonne (colonne A)
Par contre il affiche bien les données sur chaque ligne...

Je sais que je peux convertir les données de chaque ligne en autant de colonnes qu'il y a de séparateur (ça fonctionne !) mais je ne peux le faire que pour une ligne à la fois et j'en ai + de 1500 !!....

Quelqu'un peut-il m'aider svp ? Merci d'avance
Hervé
