4.1:  Introduction to Google Sheets
Google Sheets is an online spreadsheet app that lets you create and format spreadsheets and simultaneously work with other people.  You will find that it works very similar to Microsoft Excel. Here's what you can do with Google Sheets:
  • Import and convert Excel, .csv, .txt and .ods formatted data to a Google spreadsheet
  • Export Excel, .csv, .txt and .ods formatted data, as well as PDF and HTML files
  • Use formula editing to perform calculations on your data, and use formatting to make it look the way you'd like
  • Chat in real time with others who are editing your spreadsheet
  • Create charts with your data
  • Embed a spreadsheet — or individual sheets of your spreadsheet — on your blog or website
