You can always cast json to jsonb:
test_db=# create table t (a integer primary key, b jsonb);
CREATE TABLE
test_db=# insert into t (a, b) values (1, to_json('a'::text)::jsonb);
INSERT 0 1
test_db=# select * from t;
a | b
---+-----
1 | "a"
(1 row)

test_db=# insert into t (a, b) values (2, to_json('{"a","b","c"}'::text[])::jsonb);
INSERT 0 1
test_db=# select * from t;
a | b
---+-----------------
1 | "a"
2 | ["a", "b", "c"]
(2 rows)
