Dear RichardSpas,
Greetings! Thank you for posting in the Microsoft forum.
The link mentioned in your post describes the process in Excel desktop app, but I believe you are using Excel for the web, right?
If you are using Excel for the web and wanted to create a workbook link, follow the steps below:
- Open two workbooks in Excel for the web. They should be stored in either OneDrive or SharePoint.
- In the source workbook, copy the range.
- In the destination workbook, “paste links” via the right click menu or via paste special on the Home tab.
The gif below provides a brief demonstration.
For reference information, see Workbook Link support in Excel for the web - Microsoft Community Hub
If my understanding above is not consistent with yours, you can also post back and point that.
Your understanding and patience will be highly appreciated. I hope that you are keeping safe and well!
Sincerely,
Neha | Microsoft Community Moderator
