Well, the answer is "Yes", but it's probably not what you want.
In cell formulas, Char(9) evaluates to a Tab, but it will appear as a
hollow box in Excel. If you copy and paste it to an application that is
'tab aware' - say Notepad, you will see a tab.
However, if you copy what you just pasted into Notepad and paste it
back into Excel, anything to the right of the tab goes into the next
cell - that's because Excel treats tabs as a command to move to the next
cell.
BTW, the Concatenate function is a good way to get tabs and other
'non-printing ASCII characters' into text strings, but as you see, what
you get may not be what you expected or wanted...
