- [Instructor] In this chapter,…we're going to explore several common data formats…that we can use with our files…and the first of those is CSV.…CSV is an abbreviation for comma-separated values…and it's frequently used when we want to export data…from databases or spreadsheets…and be able to import it somewhere else.…It's a good file interchange format.…The way that a line in a CSV file would look is…that you have a number of values…that are separated by commas.…Here you can see I've got someone's name,…their street address, their city, and their state.…
That's four values and each one of them is separated…by a comma.…That makes it easy to go back in parts…and be able to figure out each of those values again…when we import it.…This is one line in a CSV file.…Presumably in a file there'd be multiple lines,…one per person, and they would all have the same number…of values all in the same order.…Ruby has the ability to work with CSV files…with part of the Ruby Standard Library.…That means the code for CSV files isn't loaded by default,…
