Comma-Separated Values (CSV)

CSV 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. It is widely supported across various applications and programming languages for data exchange and storage due to its human-readable and lightweight nature.

Also known as: CSV, Comma Delimited, Comma Separated Values, CSV file, Comma-separated

Why learn Comma-Separated Values (CSV)?

Developers should learn CSV for handling data import/export tasks, especially when working with spreadsheets, data analysis tools, or APIs that require simple data interchange. It is essential in scenarios like data migration, logging, or when interoperability with non-technical users (e.g., via Excel) is needed, as it avoids complex dependencies.
