this misses odd instances with adjacent spaces, since you used the opening , as a trailing , -- You must do it twice.

Also kills leading and trailing spaces, more than was requested originally, but gets past the double run need of patterns with two commas.

Does that work -- usually putting ^$ inside |(\) is NG.
You have to do it twice for ", , ,"!
None of us took care of the first or last field except your sed -r (but needs to run twice)! I would put '^' second in the (|) list, as less often true, for speed.
Hi, I found out this works by trying it out. Good point about the ^ in the second part and especially the ,,, or more situation. I hadn't thought of that... . I also realized that looking for ␠* is less efficient than ␠␠*. So I think the best option is to run twice, not by piping , but by using a loop and leaving the g flag in (out is less efficient):
or GNU sed.
or some older seds:
of course every space can be replaced by [ \t] if the need arises.

Reason: The g flag was missing from the middle (sed -r ) solution
