Hi - I'm sure this is covered in some docs somewhere, but it's hard to
know what to search for.

I have a spreadsheet (using Excel 2003 SP1) in which I have a number of
rows that have an "ID" field taking the format "X.X.X.X" where X is a
number from 0 to 100. Like this:

1.1.0.0 blah blah rest of row
1.1.2.4 blah blah rest of row
1.1.3.0 blah blah rest of row
1.0.0.0 blah blah rest of row
1.1.3.2 blah blah rest of row
1.1.3.1 blah blah rest of row
1.1.1.1 blah blah rest of row
1.1.3.0 blah blah rest of row
1.1.1.3 blah blah rest of row
1.1.2.5 blah blah rest of row
1.1.1.2 blah blah rest of row
.... Etc.

How can I sort these rows so they look like this (i.e. in numerical
order by ID number):

1.0.0.0 blah blah rest of row
1.1.0.0 blah blah rest of row
1.1.1.1 blah blah rest of row
1.1.1.2 blah blah rest of row
1.1.1.3 blah blah rest of row
1.1.2.4 blah blah rest of row
1.1.2.5 blah blah rest of row
1.1.3.0 blah blah rest of row
1.1.3.1 blah blah rest of row
1.1.3.2 blah blah rest of row

Thanks for any tips!
