Build File Converting Application with Symfony

This tutorial demonstrates how to create a Symfony application that converts between four popular data formats - CSV, JSON, SQL, and XLSX. The application is structured in a way that allows for easy addition of new formats in the future. Prerequisites include basic understanding of PHP and Symfony, PHP 8.2 or above, Composer globally installed, Symfony CLI, and a JavaScript package manager (npm). The tutorial covers setting up the project, creating entity classes, repository classes, and services for reading, writing, and conversion between different file formats. It also includes creating form objects, controllers, and view templates to handle incoming requests and render application views. Finally, it demonstrates how to install Tailwind CSS and Flowbite to beautify the display of the application.
