CSV
CSV (Comma-Separated Values) is a simple, plain-text file format used to store tabular data, such as spreadsheets or databases, where each line represents a row and values are separated by commas or other delimiters. It is widely supported across various applications and programming languages due to its human-readable and lightweight nature, making it a common choice for data exchange and import/export operations.
Developers should learn and use CSV when working with data export/import, data analysis, or interoperability between systems, as it is a universal format for sharing structured data. It is particularly useful in scenarios like data migration, reporting, and integrating with tools like Excel, databases, or data processing libraries, where simplicity and broad compatibility are prioritized over complex features.
