• JSON: A lightweight, text-based format for storing and exchanging structured data. Uses key-value pairs and arrays, making it ideal for APIs and configuration files.
• CSV: A simple tabular format where each line represents a row and values are separated by commas. Widely used for spreadsheets, database exports, and data analysis.
