Build a reusable React component to export arrays to Excel

A developer shares their experience and process of creating a reusable export-to-Excel button in a React application, detailing how it can be integrated into any page to download data from a JSON API response array into an Excel file. The component allows users to choose between downloading all columns or selected columns through a modal interface built using Chakra UI. The article explains the technical steps involved, such as converting an API response array into an Excel-compatible format using JavaScript, HTML, and XML. The solution involves programmatically creating a download link using the Blob API and URL.createObjectURL() method and includes details on setting up a React application and Chakra UI, along with writing functions to manage the data conversion and export process. The developer also shares insights into using helper functions for deep-cloning arrays and managing UI state with React hooks, ultimately providing a comprehensive guide for implementing a common feature request in admin dashboard projects.
