How to Convert CSV to JSON in Java
Converting data from a CSV file to JSON format is a common requirement in software development, particularly when dealing with data interchange between systems or APIs. Java, being a robust programming language, offers several methods to achieve this conversion efficiently. This post will guide you through the process using different Java libraries.
Step 1: Add Library Dependency
