There is gocarina/gocsv which handles custom struct in the same way encoding/json does.
You can also write custom marshaller and unmarshaller for specific types.
Example:
type Client struct {
Id string `csv:"client_id"` // .csv column headers
Name string `csv:"client_name"`
Age string `csv:"client_age"`
}
func main() {
in, err := os.Open("clients.csv")
if err != nil {
panic(err)
}
defer in.Close()
clients := []*Client{}
if err := gocsv.UnmarshalFile(in, &clients); err != nil {
panic(err)
}
for _, client := range clients {
fmt.Println("Hello, ", client.Name)
}
}
