How to Convert JSON Data to a String for an Axios POST Request in React

When working with APIs in React, especially during POST requests, you often need to send JSON data to the server. Using Axios as your HTTP client simplifies this process, but it's crucial to ensure your JSON data is formatted correctly. Here’s a step-by-step guide on how to convert JSON data to a string for an Axios POST request in React applications, including ReactJS and React Native with React Hooks.

Why Convert JSON to String?
