Simulation data and analysis code underlying "Formation of Hot Jupiters in Dense Stellar Clusters: host exchange and tidal migration in direct N-body simulations" (Abid, Boekholt & Correia, in preparation). Fifty realisations of a compact 300 au Plummer cluster of 32 solar-mass stars, each initially hosting one Jupiter-mass planet on a circular orbit at 5.2 au, integrated for up to 400 kyr with TIDYMESS, which evolves orbits, spins and ellipsoidal tidal deformations together with pairwise first post-Newtonian accelerations. Eleven planets reach fully circularised hot-Jupiter orbits: five migrate around their original host, and six arrive only after a three-body encounter transfers them to a new one. The deposit contains the final state of all 1600 planets with their fate classification; the 25 close-in giants and the 11 confirmed hot Jupiters with the full set of tabulated properties; per-realisation records of termination time, tightest final pair and angular-momentum drift; the catalogue of all 41,571 episodes in which a pair of stars closed to within 50 au; time series for each confirmed hot Jupiter including the secular diagnostics; the observed comparison sample; the initial-condition generator with the random seeds needed to reproduce every realisation; and the eighteen scripts that produce every figure and table in the paper. The README documents the contents, the units and definitions of every column, and two limitations that affect how the files should be read.
