Yes. If your expression is say a m X n X k array you will find k
worksheets in the file resulting from Export["filename.xls",array,"XLS"]

I am not aware of a way to write to a given worksheet. Possibly,
a similar command syntax will work with Export.

Export does this by default

I don't know whether this is possible or not but I strongly
doubt that it is.

One thing to keep in mind. The limits for the size of arrays in
Mathematica greatly exceed those allowed in some versions of
Excel. Obviously, there is no way for Export to fix this.

Also, the amount of time Mathematic uses (at least on my system)
to export to XLS format gets to be quite significant for large
files. Simply put, XLS is not a native Mathematica format and a
lot has to be done to convert things into this format.
