find what:

^([0-9]*\.[0-9]*),([0-9]*\.[0-9]*)$

replace with:

\2,\1

Answer 3

Try with following regex:

(\d+\.\d+),(\d+\.\d+)

and replace it with:

\2,\1

Answer 4

Search for:

([0-9]+(\.[0-9]+)?),([0-9]+(\.[0-9]+)?)

Replace with:

\2,\1

This catches numbers like 1, 1.1 but not 1. or .5. My previous regexp ([0-9]+.?[0-9]*),([0-9]+.?[0-9]*) would allow for 1..
