How do I determine Fourier coefficients from a discrete data set?

I have about 10,000 points of data plotted in equal intervals of time ( 0.2 msec intervals). I an interested in determining the fourier coefficients of this data by converting these discrete data points into a continuous signal. How do I do that?
