I would guess so however I have never tried it.
One thing I would try if you run into trouble. Have oyu noticed how, in excel, the "raw data" of the data is a number? For example type 37318 in a cell, and format it to date, and you get 03/03/02. This is called (or so I am told) a julian date. There is a julian date to date UFL on the Crystal Decisions website. If you might run into problems, download that UFL, convert the dates and try it again.
Let me know if this is an issue. I rarely work with excel as a data source (thank god) so I have never tested this julian date to date function. Software Support for Macola, Crystal Reports and Goldmine
