I made something a while back that compares lists/tables and visually shows results: http://skratchdot.github.io/list-tool/ http://skratchdot.github.io/list-tool/ Some of the algorithms aren't optimized (as to keep results in the order they were processed). It was more of an experiment to play with web workers and responsive design.
