While CSV files lack complex formatting, they are lightweight, easy to read and write, and widely supported by various software applications.

What is the purpose of a Comma-Separated Value?

To import a CSV file into a database, you can use specialized software or programming languages that support database operations. These tools often provide functionalities to map CSV columns to database tables and handle various data transformations during the import process.

In conclusion, a Comma-Separated Value (CSV) is a plaintext file format widely used for storing and exchanging tabular data.
