You’ve probably noticed there are lots of different options for saving your workbook. I would recommend saving your workbook in the cloud, so either using OneDrive or SharePoint, and the reason why is well you now have a backup of your workbook. If something happens to your computer, your workbook’s safe. It also auto saves as you’re working, so once again, you don’t have to worry about losing any of your data. You also get access to something called version history. This way, let’s say you make some changes that you didn’t intend to make to your workbook, well you could simply jump back to a previous version, and also one of the biggest benefits, you can collaborate and work together with others on your workbook at the same time.
