A great tutorial for those wanting to get started with Google Sheets.
If you haven't been in Google sheets in the past few months, you may want to check it out. Google has made some great changes to make Google Sheets function more like other spreadsheet programs you may be familiar with.
My favorite feature is the "Explore" data button. This allows you to "Ask a Question" about your data and, Google Sheets will provide the answer and the formula used to get the answer. It really makes the spreadsheet much more user friendly.
