How to modify the following VIM regex to work with white space after commas? -

i took regex question: what vim command(s) can used quote/unquote words?

:%s/\([^,]\+\)/"\1"/g 

it turns this:

foo,foo bar,bar@foo,foo# bar,bar$ foo# 

into this:

"foo","foo bar","bar@foo","foo# bar","bar$ foo#" 

i modify regex work this:

foo, foo bar ,bar@foo ,foo# bar, bar$ foo# 

turning this:

"foo", "foo bar", "bar@foo", "foo# bar", "bar$ foo#" 

any suggestions?

something work

:%s/\s*\([^,]\+\)/ "\1"/g | %s/^ // 

match leading whitespace before putting capture group. put space before capture group in quotes. put , space in first column need remove space use second substitute command.
