Generation of random numbers from a Lognormal distribution

Hi everybody,
I have to simulate losses occurring in a portfolio of non-life policies and I need to generate a several thousands of random numbers but from a Lognormal distribution. and repeat the operation many thousands of times. I tried the Excel add-in instrument "data Analysis" but it proposes only normal, poisson and binomial distribution as sources of random numbers.
Can you suggest any other way of extracting numbers from a Lognormal distribution?
I thank you in advance for your usual valuable assistance.
Marco.
