Follow-Up: Sadly no longer compatible.

Looks like FB changed it’s export format:

[{"timestamp": 1566833332,"attachments": [],"data": [{"post": ""},{"update_timestamp": 1566833332}],"title": ""}]

This is not what Ditchpost expects.

The posts file is also no longer posts/your_posts.json but posts/your_posts_01.json
