Thanks James for the reply.
Unfortunately clearing my cache does not help, as the issue is happening in my Excel client version, so nothing to do with my cache.
I actually did call QB Help,and when they understood it was a formatting issue they said that it was out of their scope.  They are only responsible for getting the data into Excel, and nothing beyond that.  I take some issue with this however as the data did not get into Excel properly.  The data in question was text, not a number, so one could not use formulas on it, and I had to manually retype it.
If you have any other ideas please let me know.
