Hello,

I understand that this thread concerning COCO JSON export is closed, but it never got an answer. I am interested in what the answer is. Could someone please help me out? It is causing some issues with a few models that I am trying to run.

Hi @RhysDeLoach!  
I’m sorry you’re running into this issue. I will elevate this to the appropriate team. To help me triage faster, do you give me permission to access your workspace?

Thank you for your patience!

Hi @RhysDeLoach!  
I followed up with our team and unfortunately you can’t remap the super-category class, this is just part of the COCO format specification. Roboflow does not support multi-level categorization.

Apologies for the inconvenience, thank you again for following up on this!!
