There are a few ways to say "I am happy that you are my friend" in French, depending on the level of formality and the nuance you want to convey:

Formal:

* Je suis heureux/heureuse que vous soyez mon ami/amie. (This is the most formal and literal translation.)

Informal:

* Je suis content/contente que tu sois mon ami/amie. (This is more casual and friendly.)

* Je suis ravi/ravie de t'avoir comme ami/amie. (This emphasizes your joy and happiness about the friendship.)

* C'est super d'avoir un/une ami/amie comme toi. (This is a more playful way to express your happiness.)

You can also use the verb "aimer" (to love) instead of "être" (to be) to express a deeper feeling:

Remember to choose the appropriate gender for "ami/amie" based on the person you are talking to.
