I want to transform this JSON for import in a database what would be the best practice when using the standard transformers?

{

"day",
"domain",
"subject_identifier",
"kpi_type_code",
"kpi_count",
"kpi_value_min",
"kpi_value_max",
"kpi_value_avg",
"kpi_value_last",
"kpi_alert_condition_lower_limit_last",
"kpi_alert_condition_upper_limit_last",
"kpi_value_extremum_ok",
"kpi_value_avg_ok"
],
"values":[
[
