What CSV and JSON files are

CSV

CSV (Comma-Separated Values) is a plain text format for storing tabular data where each row is a line and values are separated by commas. It is universally compatible with all spreadsheet and database applications.

JSON

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is widely used for APIs, configuration files, and data storage.
