Data Plotting of Accelerometer data

I am trying to import data from accelerometers for fft analysis. I know the data is supposed to be a wave, but looks as such.

Can this still be transformed or is it not possible?

How you are impoting the data. Where the data is, how the data is?

sorry to be so direct , but your data seems completely broke. How was that recorded ? are you sure your equipment is working fine ?

[Mason Condren]

Yes I figured out the problem, when imported to excel the data was overlapping on the timesteps. I created a new column to create equidistant time steps with the frequency in mind.

Godd news !

you still need help for the fft code or you're fine ?
