**Abstract:** In this review, a short description of exceptional field theory and its application is presented. Exceptional field theories provide a U-duality covariant description of supergravity theories, allowing addressing relevant phenomena, such as non-geometricity. Some applications of the formalism are briefly described.

**Keywords:** T-duality; exotic branes; non-geometric backgrounds; exceptional field theory
