Of course.
Use https://golang.org/pkg/bufio/#Scanner to parse each line.
Then use https://golang.org/pkg/strings/#SplitN `Split(line, ":", 2)` to
split the key and the value (`key: value`).
Finally parse the value using
https://golang.org/pkg/encoding/json/#Unmarshal.
Not tested.

Try something like
https://play.golang.org/p/eHEjKINz9aW
func extract(r io.Reader) {
dec := json.NewDecoder(r)
for {
var el s
err := dec.Decode()
if err == io.EOF {
break
}
log.Println(el)
}
}

If the file is consistent parse the Json part out of each line and just
unmarshal it.
