+# Pretty Printing JSONB Rows
+
+Who needs a document store when you can just use PostgreSQL's `JSONB` data
+type? Viewing rows of `JSONB` output can be challenging though because it
+defaults to printing them as a single line of text.
+
+```sql
+> select '{"what": "is this", "nested": {"items 1": "are the best", "items 2": [1, 2, 3]}}'::jsonb;
+                                      jsonb
+----------------------------------------------------------------------------------
+ {"what": "is this", "nested": {"items 1": "are the best", "items 2": [1, 2, 3]}}
+(1 row)
+```
+
+Fortunately, Postgres comes with a function for prettying up the format of
+the output of these rows --
+[`jsonb_pretty`](https://www.postgresql.org/docs/current/static/functions-json.html)
+
+```sql
+> select jsonb_pretty('{"what": "is this", "nested": {"items 1": "are the best", "items 2": [1, 2, 3]}}'::jsonb);
+            jsonb_pretty
+------------------------------------
+ {                                 +
+     "what": "is this",            +
+     "nested": {                   +
+         "items 1": "are the best",+
+         "items 2": [              +
+             1,                    +
+             2,                    +
+             3                     +
+         ]                         +
+     }                             +
+ }
+(1 row)
+```
