Macro to duplicate a string but increase the number in parentheses

Hi all,

I have some text that reads like

if ([x - (1)] *1.00001 > [X])
{
asdfasdfadsf
}

All in Cell A1

where x and asdfasdfadsf are irrelevant text.

I'm looking to replicate this over and over, increasing the (1) by 1 every time until 50,000.
Each replication should be placed in the cell below.
Note that 1.0001 remains unchanged.

So Cell A2 would read


if ([x - (2)] *1.00001 > [X])
{
asdfasdfadsf
}

Cell A3 would read

if ([x - (3)] *1.00001 > [X])
{
asdfasdfadsf
}
.......

And Cell A50000 would read

if ([x - (50000)] *1.00001 > [X])
{
asdfasdfadsf
}


Any and all help appreciated!

with your data in A1, change the (1) to Row(1) and fill down to A50000
