Hi Sekhar,
I just tried something, I am not sure whether this is really efficient. Just sharing what I did.
Suppose your formula is in sheet1 cell A1, the formula is "=Sheet2!A1".
Now in the sheet1 itself,goto Formulas, Trace Precedents.
You will get a black arrow & a box.
Double click on the arrow, you will get a "Go To" dialog box with a path mentioned.
The path will be of sheet 2 cell A1 in our case.
select the path, press OK, you have reached !
