comment Importing from Excel
Marty Cohen's answer below is sage advice--I do the same when I'm trying to import data from a spreadsheet. If that's not an option, then you should probably make your spreadsheet accessible to the SE community. One thing I'll mention is that your import command should start with a capital letter (as do all built-in Mathematica functions).

comment Plotting Partial Sums of Fourier Series
Once you fix the sum, you should be able to plot what you want by just doing Plot[Append[partialsums,f[x]],{x,-4 Pi, 4 Pi}].

comment Plotting Partial Sums of Fourier Series
There's a k in the denominator of the sum (actually, two) and your index for k goes from 0 to n, so the sum is always indeterminate.
