Je dois additionner les paiements effectués par chaque entreprise chaque mois (les données sont réparties sur 2 ans). Donc, pour cet exemple, je dois utiliser Excel pour trouver quand Acme a payé en mai et ajouter tous ces paiements. Pareil pour les autres. Je suis un peu inexpérimenté et je n'ai pas réussi à trouver un bon exemple de quelqu'un qui a fait cela dans le passé.
La sortie doit être dans une autre feuille, idéalement organisée comme suit:
