Convert

Before
{"name": "john, jane, gordon, matthew"} 

               to 
After

Answer 1

If your Json file has entries in a single line, then this AWK program works for your example:

{
    sub(": *",": [")
    sub("}","]}")
    gsub(", *","\",\"")
    print
}

If your data is in a single line, replace sub with gsub .

Answer 2

如果所有行的格式都相似，请尝试一下

 awk '{print gensub(/\"/,"[","3")}' | awk '{print gensub(/\"}$/,"]}","")}' filename

Answer 3

I think sed is also good like in this case

$ sed -r 's/"([^"]+)".*"([^"]+)"/{"\1": ["\2"]}/; s/ ?, ?/","/g' file
{{"name": ["john","jane","gordon","matthew"]}}
