When an SQL Editor tab is selected, the most important items on the main menu bar are the Query and Edit menus.
SQL Query Menu
The Query menu features the following items:
Execute (All or Selection): Executes all statements in the SQL Query area, or only the selected statements.
Execute (All or Selection) to Text: Executes all statements in the SQL Query area, or only the selected statements, and displays it in plain text like the standard MySQL command line console.
Execute Current Statement: Executes the current SQL statement.
Execute Current Statement (Vertical Text Output): Executes all statements in the SQL Query area, or only the selected statements, and displays it in plain text like the MySQL command line console does vertically (\G).
Explain Current Statement: Describes the current statement by using the MySQL EXPLAIN statement.
Visual Explain Current Statement: Visually describes the current statement, based on EXPLAIN information provided by MySQL Server 5.6 and above. MySQL Workbench parses the EXPLAIN (JSON) output from MySQL server 5.6+, and outputs a visual representation.
Stop: Stops executing the currently running script.
Stop Script Execution On Errors: If enabled, MySQL Workbench stops executing the a query if errors are found. It can be enabled/disabled from this menu.
Limit Rows: By default, the number of returned rows (LIMIT) is 1000. Values defined here affects subsequent statements. The number ranges from 10 to 50000, and "Don't Limit".

The dialog enables you to select which result set you wish to export, the file format (CSV, HTML, XML), and the name and location of the output file. Then click Export to export the data.
The Edit menu features the Format submenu. The Format submenu includes the following menu items:
