  We review E$_{6(6)}$ exceptional field theory with a particular emphasis on
the embedding of type IIB supergravity, which is obtained by picking the
GL$(5)\times {\rm SL}(2)$ invariant solution of the section constraint. We work
out the precise decomposition of the E$_{6(6)}$ covariant fields on the one
hand and the Kaluza-Klein-like decomposition of type IIB supergravity on the
other. Matching the symmetries, this allows us to establish the precise
dictionary between both sets of fields. Finally, we establish on-shell
equivalence. In particular, we show how the self-duality constraint for the
four-form potential in type IIB is reconstructed from the duality relations in
the off-shell formulation of the E$_{6(6)}$ exceptional field theory.
