What happens to data when you save it as a CSV file?

When you save data as a CSV (Comma-Separated Values) file, the data is converted into a plain text format where each value is separated by a comma, and each row corresponds to a new line. This format allows for easy readability and compatibility with various applications, including spreadsheet software. However, it does not retain any formatting, formulas, or complex data structures, making it suitable for simple data representation but limited in functionality. CSV files are widely used for data exchange between different systems due to their simplicity and versatility.
