You can format your data through GPT instructions have one doc that is a read first that indexes your data documents
In instructions tell it to read that first at first user prompt and list functions help. If you index each doc by name with sub indexes in docs it can read and if you put how to read in instructions it will follow your function format
It won’t cost you much but it may take you time. You have to explain to it how to organize the data
You just need to build your functions
Without that it’s just data it needs structure and gpt needs to be trained to use it IE told how to.
