I am having a few big files sets of HDF5 files and I am looking for an efficient way of converting the data in these files into XML, TXT or some other easily readable format. I tried working with the Python package (www.h5py.org), but I was not able to figure out any methods with which I can get this stuff done fast enough. I am not restricted to Python and can also code in Java, Scala or Matlab. Can someone give me some suggestions on how to proceed with this?

Thanks,

TM

Mathias711's method is the best direct way. If you want to do it within python, then use pandas.HDFStore:

from pandas import HDFStore

store = HDFStore('inputFile.hd5')

store['table1Name'].to_csv('outputFileForTable1.csv')
