This course will teach you how to read data in various formats from an internal or external source using the Ruby programming language. It will also teach you how to represent data programmatically and save it to a file
for later use.
Processing data from a third party provider in JSON or CSV format is essential for communicating with other systems and representing complex information. In this course, Reading and Writing Data with Ruby, you’ll learn to read and parse data in JSON and CSV format using Ruby’s standard library and interact with various sources that make use of these
formats including local files and information returned by web services. First, you’ll explore how data is structured using either JSON or CSV including where one format is used over the other. Next, you’ll discover how to read and write JSON and CSV data to and from a local file and how it is represented natively using Ruby’s data types. Finally you’ll
learn how to apply processing of JSON data using Ruby by interacting with an actual web service. When you’re finished with this course, you’ll have the skills and knowledge of reading and writing data with Ruby needed to create applications that process data from a file and interact with third party services that use JSON to represent data.

Course Overview Hi everyone. My name is Raphael Alampay, and welcome to my course, Reading and Writing Data with Ruby. I am currently a software developer and a Pluralsight author, with courses and tutorials in the programming and machine‑learning domains. Have you started out Ruby programming and want to extend your skills storage, adding data‑driven features to your application? Do you need to create logical routines that process data coming from some structured information? Do you want to enable your application to talk to other services on the web? In this course, we'll be doing just that. Major topics include referencing and creating files with Ruby, parsing CSV and JSON‑formatted data, fetching and processing data from web services. By the end of this course, you'll be equipped with the fundamentals on reading, writing, and parsing files from Ruby. However, before you decide to start, you should already be familiar with basic Ruby syntax, programming terminologies, and of course the passion to learn more. To put things into practice, every module builds towards writing a simple application that fetches the price of Bitcoin against the US dollar from a third‑party service provider and saves the data to a file for archiving purposes and post processing. From here, you should be able to extend the concepts to add more data‑driven features to your Ruby application, and see if you can apply it to other more advanced Ruby programming courses at Pluralsight, and level up your skills. I'm looking forward to accompanying you in your journey towards learning more about modern Ruby programming in this course, Reading and Writing Data with Ruby, here, at Pluralsight.
