Are you sure you can read the binary file (.jsonlz4) with this script as you state in the comment?

Doesn't work on windows7

  File "open.py", line 26, in <module>
    parsed = json.loads(f.read())
  File "C:\python\\lib\encodings\cp1250.py", line 23, in decode
    return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 247: character maps to <undefined>

Yes, the description is not complete, I understood what the author was trying to do by going to this blog page

In fact he used this script to convert the binary file beforehand.

I haven't see these comment....

It's a one shot script I've done and find that might be helpful (And in fact, it is :))

As @BasicAcid said, you have to use dejsonlz4 first to make it works

git clone https://github.com/avih/dejsonlz4
cd dejsonlz4
gcc -Wall -o dejsonlz4 src/dejsonlz4.c src/lz4.c

./dejsonlz4 [nom_du_fichier_jsonlz4]
