+# Output Explain Query Plan In Different Formats
+
+The output of an [`explain` (or `explain analyze`) query
+plan](https://www.postgresql.org/docs/current/sql-explain.html) for a given
+query defaults to a `TEXT` format that is meant to be read by a person.
+
+```sql
+> explain (analyze) select title from books where created_at > now() - '1 year'::interval;
+                                           QUERY PLAN
+-------------------------------------------------------------------------------------------------
+ Seq Scan on books  (cost=0.00..1.28 rows=5 width=32) (actual time=0.011..0.017 rows=22 loops=1)
+   Filter: (created_at > (now() - '1 year'::interval))
+ Planning Time: 0.052 ms
+ Execution Time: 0.027 ms
+(4 rows)
+```
+
+If we instead want the query plan in a standardized format that is parseable
+and readable by a program, we can specify an alternate format like `JSON`,
+`YAML`, or `XML`.
+
+Here is the same plan with `format json`:
+
+```sql
+> explain (analyze, format json) select title from books where created_at > now() - '1 year'::interval;
+                           QUERY PLAN

+I present all four formats for a complex query plan [in this
