(Googling "convert > XML to JSON" shows up tons of transcoding options.) Artur can perhaps give a better answer, but my impression with xml is that it is too generic. You can do a lot of stuff with it, but in the end that requires to have some clever xslt or similar thing which for me basically means the same amount of work as simply exporting it in the desired format in the first place. So what's the use of a gretl bundle written out in xml from, say, Python's point of view? Well, given the nice xml tools for Python I can imagine it's not too difficult to get a tailor-made solution to grab the matrices in there. So yes, maybe the json thing isn't needed.

For target languages without such tools my first impression is that reading and processing json is simpler.
