Hi Jason,
A polite note or phone call to your data administrator requesting restore from last night's
backup, and letter from your manager that no other systems are affected.
I expect that person is you, since you deleted it from the server.
Someone might be able to recover all or most of a deleted file from hard drives, but it
is not part of Excel, and if you don't recover the entire file unlike a flat file listing, it
probably won't do you much good. You might look in the same directory for a backup
file .bck or .bak extension if your Excel was set up that way when a Save As was done
like when the file was originally created. Also look for files with names in hex that do
not have an extension.
