## 5.2.5.1 About Blueprint Designer

You can access Blueprint Designer by clicking the name of a blueprint on the Data Generator home page.

Use the tree view on the left to select a blueprint, table, column or custom data source object and modify its attributes.

Create new tables, columns, and custom data sources using the context menu.

Using the Generate Data and Preview Data buttons, you can preview data for the tables and columns, and export the data to a JSON, CSV, or SQL file. If a table exists in the schema with the same name, data can be inserted into the corresponding columns.

Click the Options icon (wrench) for shortcuts for exporting and deleting blueprints.
