Introduction

In the world of web and mobile development, handling data formats like JSON is a critical skill. If you are working with React Native and need to modify a JSON response, you may encounter a scenario where the original response structure does not meet your needs. For instance, you may want to transform a complex JSON object into a simpler array format.

In this guide, we will explore how to modify a JSON response to achieve your desired structure. We’ll break down the process step-by-step, ensuring that it’s easy to follow. By the end of this post, you will know exactly how to manipulate JSON data within a React Native application.

The Problem

Let’s start with a typical scenario:

You have a JSON response structured like this:

The question arises: How can you achieve this in React Native?

The Solution

To tackle this problem, we must first ensure that we have a valid JSON string that can be parsed into a JavaScript object. Once parsed, we can extract the values and combine them into a single array. Below is a step-by-step breakdown of how this can be achieved.

Step 1: Parse the JSON Response

First, we need to parse the JSON string into a JavaScript object. This can be achieved with the JSON.parse() method. Here’s how to do that:
