Dear Dick_Y
Welcome to Microsoft Community.
We understand that the data type in your Excel is incorrectly displayed.
According to your description, "Data Type" and "Stock" are not displayed in your Excel ribbon. We need to confirm with you:
What is your Excel version? Microsoft 365 or other?
The stock and data type functions can only be used in Microsoft 365 Personal or Family versions. Please make sure that the version activated in your Excel is Microsoft 365.

If you are sure you are using the correct version, you can try to add the corresponding ribbon information in "Customize Ribbon" to help confirm:
Open Excel and click the File tab-Options-Customize Ribbon.
Or, right-click a blank area in the ribbon and select Customize Ribbon from the context menu.
Under Choose a command, select Main Tabs. Click the Plus (+) icon next to Data Labels. Add the data type to the ribbon.
Click OK to close the Excel Options window. Navigate to the Data tab and verify that the data type is present.
You can try to see if this helps you further confirm whether the function is displayed correctly.
