I am looking for high quality Random Number Generator(RNG) similar to Mersenne Twister as a comprehensive MS OFFICE EXCEL add-in, enable users to generate random number in Excel VBA for Monte Carlo simulations.

One of the software that can meet this requirement is the Excel version of "EasyfitXL" software from Mathwave Technologies. However, this publisher site is no longer active.

Excel VBA have its own RNG called "Rnd" but I was told that it is NOT a good quality RNG. Where I can get GOOD quality RNG software that can add-in to Excel VBA to do Monte Carlo simulations ?

Regards

James
