If you rename a text file's extension as .csv, will it become a csv file ? Why/why not ?

Renaming a text file's extension to ".csv" does not automatically convert it into a CSV (Comma-Separated Values) file. To create a CSV file, we need to ensure that the file's content adheres to :

1. Content Format — A CSV file is structured with data organized into rows and columns, with each field separated by a delimiter, typically a comma (,).
2. Delimiter Usage — CSV files require a specific delimiter (usually a comma) to separate fields.
3. File Encoding — CSV files are often encoded using standard text encodings such as UTF-8 or ASCII.
