-You are welcome

-No problem

No hay una traducción totalmente literal pero si muchas formas distintas, es igual que en español, no solo existe "de nada" puedes decir:

1. de nada

2. no hay de que

3. no te preocupes

4. no hay problema

5. Gracias a ti

Now in english I will say the most commonly used is:

1. You´re welcome

2.  No problem (no prob)

3. Not at all (First time I heard this one but I´m not in USA)

4.  Cheers (Here in UK they used a lot for simple things which are not a huge favor)

5. Don´t worry

6. It´s okey

7. Thanks to you

You're welcome. (Se escribe con una sola L, no con dos).

Not at all.

Don't mention it.

It was a pleasure.

It was my pleasure.

My pleasure.

It's OK.
