We assume you've somehow transformed your raw data into NMRView format. If you only have a transformed NMRPipe spectrum, go to your command line, cd to your fid directory, and type (replacing test.ft with the name of the nmrPipe data, and test.nv with the desired output file name).

pipe2xyz -in test.ft -out ./test.nv -nv

If you're looking at multiple spectra, you will find it handy to place all of your .nv files into one new directory. It will also probably be useful to rename your files with meaningful names, such as "protG_Nhsqc.nv". If you're coordinating your NVJ work with efforts using other programs, like AutoAssign or Atons/Candid, you may wish to keep your file names generic, like "hsqc.nv," "hnco.nv," "hn_co_cacb.nv," etc. Many of these others suggest you start your filenames with the "hn" part of the experiment name.
