You forgot to attach your csvfile, so about all I can say is:
data = csvread(filename);
ft = fft(data);

I don't think I care to pay to obtain their source code.
The part of the video I watched output attention values to the display.

I'm not going to watch that whole long video. If you want, you can tell me at what time in the video they're exporting/saving the output that you need to use, and I might take a look at it.
ft is a variable that is the output of the fft() routine. The help for the fft() routine says that it returns "the discrete Fourier transform (DFT) of X using a fast Fourier transform (FFT) algorithm." In my variable, the "f" in "ft" means Fourier, and the "t" in "ft" means transform.
