You can also use h5dump -o dset.asci -y -w 400 dset.h5

  • -o dset.asci specifies the output file
  • -y -w 400 specifies the dimension size multiplied by the number of positions and spaces needed to print each value. You should take a very large number here.
  • dset.h5 is of course the hdf5 file you want to convert

This converts it to an ascii file, which is easy imported to excel, from where you can easily save it as a .csv (save as within excel, and specify file format). I did it a couple of times, and it worked for me. source
