Export data of chatGPT as a customGPT

Hey guys,
Has anyone tried downloading your conversations with chatGPT as a JSON file and tried uploading it into your note taking tool such as notion / roam / obsidian ?

Am trying to create a customGPT with my previous conversations with chatGPT and this JSON fiel is too big.
So tried splitting it into smaller 10 MB chunks.
But with the script the format goes for a toass and the customGPT isnt working as expected.

Has anyone tried this usecase?
