I went to my Reminder List. At the top there is a button that says "download". I moved the curser over it and a message says, "download your reminder list in CSV format."  What is CSV? What can I do with my list in that format? Could I then save it in an Excel file? Sorry for the dumb questions.

yes it can be used in excel.  it means comma seperated values or comma delimited.  When you save an excel file look at the drop down of file types and you will see this one.

If you don't have excel, it can be opened by any program that will open excel files. For example, Google has free online programs that equal the Word documents such as Word, Excel, PP, and others. You can create a Google account for free and then go to the Documents center and open the file there. It willshow you the title, author, publisher, binding, and other information that is posted in the books' listings.

ETA: If you do have Excel, or a program which emmulates these programs, just double clicking on the downloaded file will open it in Excel or your other program that works with Excel files.

Thank you Ronda and Sherry as I had no clue what a CSV was either.
