Simplest way is to use a stat platform: Julia, Matlab, R that allows you to import CSV and export to HDF5.
Julia native file format is hdf5 BTW. See package HDF5 and CSV.

The above solution works neat with homogeneous datasets such as hypercubes. In case you want records, and C++ is an option for you – nonhomogeneous sets – check out H5CPP.org and take a look at pocket table examples. That will take care of the HDF5 side. And there are plenty of CSV libraries with various features around for your input.
