How Do You Match the Last Comma and Space In a List With Regex?

For example, say the list is...

Hello, World, Test, One, Ten

How would I match the last comma and space (after 1), but also not match "Ten" with it?

I've tried (,\s)$ and (,\s)[^,]*$ but that doesn't do exactly what I'm looking for...

If you don't want to match Ten you can change the match into a lookahead.

,\s(?=[^,]*$)

The pattern matches

,\s Match a comma and a whitespace char
(?= Positive lookahead, assert to the right
- [^,]*$ match 0+ occurrences other than , till the end of the string
) Close lookahead

Note that \s and [^,]* can also match a newline.
