Geojson map analysis - ChatGPT cannot read geojsons?

Hello,

This is my first post. I am not sure if it is in the correct category, apologies if it isn’t.

I am working on a project where I need to extract different insights from a geojson map. This is basically a map with certain areas of interest and what I want to do is for example understand how many areas are within 100km distance from another, or what is the level of overlap between an area and a country or continent…

I am struggling to achieve to get Chatgpt to even read the geojson files, it always finds some sort of error, no matter what changes I make to it.

I am using the UI to do so, through prompts, ChatGPT4o.

Any advice on how to make this work? Is it even possible?

Thank you all!
