separate lines in excel

I posted this in this group on saturday.

The first half is my question.

The 2nd half is the response.

My question today...

What do I do with it. I think it goes into the visual basic editor but I
have been wrong before. Thats why I am here.

If that is the case how do I run it. If not the case what do I do with it.

Can I copy and paste it?

Thanks

Question
Here is a problem I have:
123456789
134567890
135678901
1456789012
157890123
this group of numbers is in my Sheet and each line is in a row by itself and
they are in 9 different columns. for brevity I just used 9 numbers for each
line. I need to know if there is a way to auto insert a row between each
individual number. My real SS will have about 900 rows with 60 characters
per row that I have already performed text to columns on. There Can be as
few as 1 row per number or as many as 25 rows per number. in the sample
above the second number would be the dividing line Please help
