I have an Excel worksheet that lists the chapter of a document, i.e.
the first column looks like this:


1
1.1
1.1.1
1.1.2
1.1.3
etc.

now at some point I reach

1.10.1

Now I'd like to sort all my chapters, but 1.10 is sorted before 1.2.

Does anyone have a solution to this?

Thanks for any help,

Gerben
