This option will export in json file all data fields in exported blocks.
Quite obviously, this leads to very huge files (over 1Mb with default .blend)
if you do not filter the output...

Less verbose and cleaner imho.

This tool aims at exporting (parts of) a .blend file in JSON.

This makes it easy to 'read' the actual content of a .blend, to diff it, etc.

This is still very WIP, right it's OK to get the general structure of the .blend
(all its blocks), but data itself is not yet exportable.

There are also options to filter (based on keys & values regex matching) what is
exported to JSON, but this is not yet fully working as expected.
