What does the term 'CSV file' refer to?

A CSV file, which stands for Comma-Separated Values, is a straightforward file format used to store tabular data. In a CSV, each line represents a data record, and individual values or fields within that record are separated by commas. This simple and universally recognized format ensures compatibility across various software applications, making it a popular choice for data storage and transfer, especially for tasks like data import/export or maintaining mailing lists.
