I have a huge excel sheet where i need to find the address of duplicate cell value in a column.
I have given an example below, where Column B returns the address of duplicate value found in Column A. Could you please help by providing the formula for Column B result? VBA is also fine.

| A | B
1 | Apple | A4
2 | Orange | A6
3 | Mango | no-match
4 | Apple | A1
5 | Grapes | no-match
6 | Orange | A2
7 | Pineapple | no-match

I used the formula "=ADDRESS(MATCH(A1,(($A$1:$A$7)),0)+ROW($A$1)-1,COLUMN($A$1:$A$7),4)", which returned the cell address of same cell that is being searched.

Apple | A1
Orange | A2
Mango | A3
Apple | A1
Grapes | A5
Orange | A2
Pineapple | A7

I did enough search over internet, but could not find. In the above formula, I just need to ignore searching for the cell being searched. Please help.
