CSV (Comma-Separated Values) is the most widely used data exchange format, perfectly supported by Excel, Google Sheets, database systems, and various data analysis tools. Its simple structure and strong compatibility make it the standard format for data migration, batch import/export, and cross-platform data exchange, widely used in business analysis, data science, and system integration.
Protocol Buffers (protobuf) is Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data. Widely used in microservices, API development, and data storage. Its efficient binary format and strong typing make it ideal for high-performance applications and cross-language communication.
