Golang convert string in to an array

Question

I have a string that I want to convert into an array.

str := "[\"firsName\",\"lastName\", \"email\"]"
fmt.Println(reflect.TypeOf(str))
fmt.Println(strings.Split(str, ","))

This results:

[["firsName" "lastName"  "email"]]

I want the output like this:

["firsName" "lastName"  "email"]

I can get this by using strings.Replace function. But is there any better way to do this?

The example string is valid json, so you could just use json.Unmarshal with []string as the target argument. go.dev/play/p/sxFpIHiFbaW — mkopriva

instead of split use trim fmt.Println(strings.Trim(str, ",")) — Mandeep Gill

You can use strings.Trim to remove the trailing and leading unwanted character.

trimmedStr := strings.Trim("[\"firsName\",\"lastName\", \"email\"]", "[]")
fmt.Println(strings.Split(trimmedStr, ","))

str := "[\"firsName\",\"lastName\", \"email\"]"
var strArr []string
_ = json.Unmarshal([]byte(str), &strArr)
fmt.Println(strArr)
