If you add another column to your exiting table let's say your data is in
A:M, then it is column N.
In N1 enter
=MOD(ROW(),17)
and fill down column N by double clicking the fill handle twice (the fill
handle is the small solid black cross that you see when you hover over the
bottom right corner of a cell)
This will put the sequence of numbers 1 through 16, then 0 for the 17th row
continuing on down the column.
Apply Data>Filter>Autofilter and use the dropdown on column N to select 0,
and you will have every 17th row.
Thanks so much for taking the time to write out these steps, Roger. I had a
similar question, but hadn't read this post. I received the formula from
David, as well, but wasn't sure what a "helper column" was. Before I went
back to ask him, I thought I would look at a few more posts to see if it was
explained. Your explanation was exactly what I needed, too. Thanks!
