Excel is not really designed to have multiple access to the same
workbook.

There is a concept of "shared workbook" where multiple users can update
the same workbook at about the same time; when a user saves their
changes they get to see the changes made by others. There are
restrictions on what you can do in a shared workbook and there have
been some bugs in this area in the past so I would not recommend their
use.

If only one machine is updating the information and others are only
reading the information then you could use a separate workbook for the
readers with cells linked to the master workbook using formulas.
New data would not appear immediately - you would have to cause the
linked formulas to recalculate.

The program within the Office suite that is best suited for multiple
access to the same data is Access.
