Is there a tool that automatically can determine data structures?

Machine learning and NNs might help but this totally custom format is not common enough perhaps to get a good training dataset.

This is more of a question that is in the forensic analysis area. With huge amounts of data, finding the signal from the noise which requires determining data format. So this will be researched more in the AI future for sure.

Okay but short of theoretical data science, for RE, WhoCares gave you the way to do it.
