Well after some tryouts, there is an answer. Everything is same as in https://developers.google.com/sheets/quickstart/go Just changes in the main function

func write() {
    ctx := context.Background()
    b, err := ioutil.ReadFile("./Google_Sheets_API_Quickstart/client_secret.json")
    if err != nil {
       log.Fatalf("Unable to read client secret file: %v", err)
    }

// If modifying these scopes, delete your previously saved credentials
// at ~/.credentials/sheets.googleapis.com-go-quickstart.json
    config, err := google.ConfigFromJSON(b, "https://www.googleapis.com/auth/spreadsheets")
    if err != nil {
        log.Fatalf("Unable to parse client secret file to config: %v", err)
    }
    client := getClient(ctx, config)

    srv, err := sheets.New(client)
    if err != nil {
        log.Fatalf("Unable to retrieve Sheets Client %v", err)
    }

    spreadsheetId := "YOUR SPREADSHEET ID"

    writeRange := "A1"

    var vr sheets.ValueRange

    myval := []interface{}{"One", "Two", "Three"}
    vr.Values = append(vr.Values, myval)

    _, err = srv.Spreadsheets.Values.Update(spreadsheetId, writeRange, &vr).ValueInputOption("RAW").Do()
    if err != nil {
        log.Fatalf("Unable to retrieve data from sheet. %v", err)
    }

}
