How does string theory fit with QFT?

In string theory, particles is vibrating strings. However, QFT treats particles as excitations in a quantum field. Can both of these theories be correct? If so, how does them fit together?

In perturbative string theory, QFT can be viewed as an approximation of string theory. In non-perturbative string theory, there are conjectures claiming that string theory and QFT can be equivalent.

Well if QFT explains quantum particles as vibrations in a field then using string theory, you can apply each vibration's frequency according to the molecules being strings?
