When someone says “merci” we says

We say “Je vous en prie" (You’re welcome) in formal responses

We say "Avec plaisir" (With pleasure) in formal responses

We say "De rien" (It’s nothing) in casual responses.

We say “Pas de problème” (No problem) in casual responses.

We say “Il n’y a pas de quoi" (Don’t mention it) in casual responses.
