What is a CSV file?

CSV files, short for Comma-Separated Values, serve as a fundamental tool for organizing structured data in a universally understandable format. In essence, these files represent tabular data, where each line signifies a record, and the data within is separated by commas or other specified delimiters. While they are called Comma-Separated Values, it is not always the case that a comma is used as a delimiter. Other commonly used delimiters are:

• Semicolon (;)
• Full Stop (.)
• Space ( )
• Tab ( )
