Data interchange between systems typically employs various data formats, including JSON (JavaScript Object Notation), XML (eXtensible Markup Language), and CSV (Comma-Separated Values). These formats standardize how data is structured and transmitted, allowing different systems to understand and utilize the information efficiently. JSON is commonly used for APIs and web applications due to its lightweight nature and ease of use. XML is more verbose but offers flexibility, while CSV is often preferred for spreadsheet applications. Each format plays a significant role in facilitating seamless information exchange across diverse platforms.
