Convert a json which is a list of dictionaries into column/row format in Postgresql - sql

Question

I´ve a json which is a list of dictionaries with the next syntax:
[
{
"Date_and_Time": "Dec 29, 2017 15:35:37",
"Componente": "Bar",
"IP_Origen": "175.11.13.6",
"IP_Destino": "81.18.119.864",
"Country": "Brazil",
"Age": "3"
},
{
"Date_and_Time": "Dec 31, 2017 17:35:37",
"Componente": "Foo",
"IP_Origen": "176.11.13.6",
"IP_Destino": "80.18.119.864",
"Country": "France",
'Id': '123456',
'Car': 'Ferrari'
},
{
"Date_and_Time": "Dec 31, 2017 17:35:37",
"Age": "1",
"Country": "France",
'Id': '123456',
'Car': 'Ferrari'
},
{
"Date_and_Time": "Mar 31, 2018 14:35:37",
"Componente": "Foo",
"Country": "Germany",
'Id': '2468',
'Genre': 'Male'
}
]
The json is really big and each dictionary have different amount of key/values fields. And what I want to do is to create a table in postgresSQL where the key represents a column and the value a row. In the example explained above I would like table like this:
Date_and_Time | Componente | IP_Origen | IP_Destino | Country| Id | Car | Age| Genre
Dec 29, 2017 15:35:37 | Bar | 175.11.13.6 | 81.18.119.864 | Brazil | - | - | 3 | -
Dec 31, 2017 17:35:37 | Foo | 176.11.13.6 | 80.18.119.864 | France |123456 |Ferrari | - | -
Dec 31, 2017 17:35:37 | - | - | - | France |123456 |Ferrari | 1 | -
Mar 31, 2018 14:35:37 | Foo | - | - | Germany| 2468 | - | - | Male
The only solution I can think is putting the values one by one but this is no efficient at all

Answer 1

You can use jsonb_to_recordset to create record set out of your json and then use insert into to insert the records.
insert into table
select * from jsonb_to_recordset('<your json>'::jsonb)
as rec(Date_and_Time datetime, Componente text, IP_Origen text) --Specify all columns inside the table
