@seshu: I think we can achieve that without any add-in. Select the column where you want the numbers to appear in Rs.x,xx,xxx.xx format, and format the cells as custom type, and select the one something like this: Rs. #,##0.00;[Red]Rs. -#,##0.00 This will make the positive numbers appear as Rs.x,xx,xxx.xx and negative numbers as Rs. - x,xx.xx
