For a one-time job, you can use this regex (but note that with longer strings, it may not work well, use it as a means of last resort):

,(?!(?:[^"]*"[^"]*")*[^"]*$)

请参见 regex演示

• ,-逗号...
• (?!-不跟....
  • (?:-
    • [^"]*-除"
    之外的零个或多个字符
    • "-双引号
    • [^"]*"-参见上文

    • (?! - is not followed with....
      • (?: -
        • [^"]* - zero or more chars other than "
        • " - a double quote
        • [^"]*" - see above
