I can export to all other formats from the report viewer with no issues, but when I try to render to Excel, I get an exception:
[Exception: Object reference not set to an instance of an object.]
[Exception: An error occurred during rendering of the report.]

I've pinned it down to a footer cell that uses an expression to determine the TextAlign property. If I do something as simple as ="Right", I get the error. Of course, if I just use Right, there is no problem. So are expressions not supported in footer cell properties or is there possibly some fix for this?
Thanks.
The only solution would be to keep the textbox in the report body than the footer.

In case any MS folks are reading and want to reproduce this problem, here's a simple report that exhibits the behavior:
