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 programming languages, applications, and platforms due to its human-readable and lightweight nature, making it a common choice for data exchange and basic data storage.
Developers should learn and use CSV for tasks involving data import/export, data migration, and quick prototyping, as it is easy to generate, parse, and share without complex dependencies. It is particularly useful in data analysis, reporting, and integrating with tools like Excel, databases, or APIs where structured data needs to be transferred in a simple format.
