Parsing JSON Data for Use with Mapbox

When working with mapping solutions like Mapbox, being able to accurately extract geographical coordinates from external JSON data is crucial. If you've ever found yourself in a situation where you need to parse JSON from a URL for mapping, this guide is for you. We'll walk through a practical example and provide a clear solution to fetching coordinates for Mapbox.

Understanding the Problem

We frequently encounter JSON files that hold vital information such as geographical data. In this instance, the JSON structure you’re dealing with consists of a location array that includes device_id and geometry properties, which in turn contains the coordinates you want to utilize.
