You can use wildcard replacement
(http://www.gmayor.com/replace_using_wildcards.htm) to do this more easily.

However, you need to do three replacements in order to get it done correctly.
The problem is that if you immediately change all the comma decimal separators
to periods, there won't be any way to tell them apart from the thousand
separators that are periods; if you change all periods in numbers to commas,
that will catch the decimal separators also.

The solution goes like this:

- First change all comma decimal separators to some character that doesn't occur
between digits anywhere else in the document. Let's assume you can use the tilde
(~) for this. So open the Replace dialog, click the More button, and check the
Use Wildcards option. Put this expression in the Find What box:
   ([0-9]),([0-9])
and put this in the Replace With box:
  \1~\2
Click the Replace All button.

- Next change all the period thousand separators to commas. Use this expression
in the Find What (the same as before except change the comma to a period):
   ([0-9]).([0-9])
and put this in the Replace With box:
  \1,\2
Click the Replace All button.

- Finally, change all the tildes to periods. Use this in the Find What:
   ([0-9])~([0-9])
and put this in the Replace With box:
  \1.\2
Click the Replace All button.
