Can ArcGIS Pro join to existing excel worksheets the way desktop does? If not, what would be an easy workaround, if any?
With Pro 1 (Prerelease), it looks that it does not allow to join directly with Excel database like desktop.
I guess, it is not bug or limitation. Maybe, it is a part of workscope for Pro to ensure the integrity of data sources in Pro..
To solve this need in Pro, I would like to do:
1. Create a empty table in GDB;
2. Copy records from Excel into the above table in GDB;
3. Join in Pro to this new table
To finish those steps, all tools are available in Pro

Just adding to Larry's words - Pro currently supports Excel only as an Input/Output for Geoprocessing as it mentioned in its documentation.
Another option to bring an excel table is by Import it, using the Excel to Table tool.
There's an "Excel til table" tool which might help you?
