I looked through the boards, came close to finding what I needed... but they
were off a little.

I have ColA and ColB filled to about 30000 Rows. I would like a script that
compares each column, and inserts a/some rows if they dont match up. The
blank column could be inserted on either column and if there is 20 rows of
missing data, it inserts 20 rows of blanks.

Ex:
The script would
Befo
Col1 Col2
1 1
2 2
3 4
4 5
5 6
7 10

After:
Col1 Col2
1 1
2 2
3
4 4
5 5
6
7
10

Is this possible?

Thanks for the help!
