| ------ | ------ |
| Not specified | If the format is not specified, `EXPLAIN` uses the default format `row`. |
| `row` | The `EXPLAIN` statement outputs results in a tabular format. See [Understand the Query Execution Plan](/explain-overview.md) for more information. |
| `brief` | The operator IDs in the output of the `EXPLAIN` statement are simplified, compared with those when `FORMAT` is left unspecified. |
| `dot` | The `EXPLAIN` statement outputs DOT execution plans, which can be used to generate PNG files through a `dot` program (in the `graphviz` package). |
| `tidb_json` | The `EXPLAIN` statement outputs execution plans in JSON and stores the operator information in a JSON array. |
