I wrote a blog post how to use this: http://widerin.net/blog/weblate-i18next-json-parser/

Thanks for this script!

What about changing this line:

#!/usr/bin/env python2.7

into

#!/usr/bin/env python

And using 2to3 to make it possible to run it on either version of python?

@rolinh should work fine on python3

Thanks for the script!
But line 30 should be:
for key in keys[:-1]:
