Jim, thank you for your feedback! Please note that there’s no notion of content controls in Excel. Content controls feature is only available in Word.
Also, the content control API is already available in Word Online. However, content controls are currently not editable in Word Online, and this is currently being worked on. We’ll keep you posted when this is available.

Not only would the editing of user controls in the Word web application, but the addition of content controls to Excel and PowerPoint would also be great. I'm working with an open-source add-in project (https://dotnetfoundation.org/chemistry-add-in-for-word) team that would really like to be able to add the same functionality that we have in Word to both Excel and PowerPoint and maybe even OneNote!
