CSV files are a popular format for tabular data.

• A. True
• B. False
• C. Not commonly used
• D. Never used

Answer: (A)

CSV files store tabular data in plain text, with each row on its own line and fields separated by commas (or other delimiters). This plain, human-readable format is extremely popular because it’s simple to create and read, and it’s supported by virtually every data tool, programming language, spreadsheet software, and database system. Its lightweight nature makes it ideal for quick data exchanges, small to moderately sized datasets, and scenarios where you want wide compatibility without needing special software or schemas. While other formats exist that offer more structure or efficiency, CSV remains a go-to for interoperability and ease of use.
