Converting hdf5 to csv or tsv files

Question

I am looking for a sample code which can convert .h5 files to csv or tsv. I have to read .h5 and output should be csv or tsv.

Sample code would be much appreciated,p

Answer 1

Python:

import numpy as np
import h5py
np.savetxt(sys.stdout, h5py.File('foo.h5')['dataname'], '%g', ',')

Some notes:

1. sys.stdout can be any file, or a file name string like "out.csv".
2. %g is used to make the formatting human-friendly.
3. If you want TSV just use '\t' instead of ','.
4. I've assumed you have a single dataset name within the file (dataname).
