Convert TSV to JSON refers to the process of transforming data stored in a Tab-Separated Values i.e. TSV file into the JavaScript Object Notation i.e. JSON format. This conversion is essential because TSV files organize data in rows and columns using tab characters, whereas JSON structures data in key-value pairs, making it a more suitable format for web applications. Additionally, JSON is a widely accepted data interchange format that can be easily parsed by most programming languages, thereby simplifying data manipulation and integration. Converting TSV to JSON also enables smoother integration with modern web services and APIs, ensuring interoperability across different platforms and enhancing overall data management.
