Suppose you have a small business, and you want to keep track of how much money you're making and spending each day. You also want to predict how much you'll make in the future. A "spreadsheet" is perfect for this.

Imagine you have a big collection of information, like a list of your favorite books or a list of your friends' names and their ages. For example, if you have a list of books, you can put the book title, author, and year published all in one line, separated by commas. 

CSV stands for comma-separated values and is stored as a text file with all entries separated by -you guessed it - commas.

It's great for storing and exchanging data on the internet.
