Comma-Separated Values (CSV)

A Comma-Separated Values (CSV) file is a simple text format used to store tabular data, like a spreadsheet. Each line represents a row, and within that line, individual pieces of data—called fields—are separated by commas. This format makes it easy to share and import data between different programs, such as database systems or spreadsheet applications. CSV files are lightweight, plain text, and human-readable, making them a popular choice for data exchange and storage when a straightforward, lightweight format is needed.
