Abstract	The Belle and Belle II experiments have collected a 1.4 ab-1 sample of e+e- collision data at centre-of-mass energies near the Upsilon(nS) resonances. These samples contain a large number of e+e- -> ccbar events that produce charmed mesons and baryons. We present searches for rare flavour-changing neutral current c->ul+l- processes in several decay modes. Further, we study several decays of the Lambda_c and Xi_c to determine branching fractions, as well as CP asymmetries in singly cabibbo-supressed decays.
