<a name="tgw-export-route-tables"></a>

You can export the routes in your transit gateway route tables to an Amazon S3 bucket. The routes are saved to the specified Amazon S3 bucket in a JSON file.

**To export transit gateway route tables using the console**

1. Open the Amazon VPC console at [https://console.aws.amazon.com/vpc/](https://console.aws.amazon.com/vpc/).

1. On the navigation pane, choose **Transit Gateway Route Tables**.

1. Choose the route table that includes the routes to export.

1. Choose **Actions**, **Export routes**.

1. On the **Export routes** page, for **S3 bucket name**, type the name of the S3 bucket.

1. To filter the routes exported, specify filter parameters in the **Filters** section of the page.

1. Choose **Export routes**.

To access the exported routes, open the Amazon S3 console at [https://console.aws.amazon.com/s3/](https://console.aws.amazon.com/s3/), and navigate to the bucket that you specified. The file name includes the AWS account ID, AWS Region, route table ID, and a timestamp. Select the file and choose **Download**. The following is an example of a JSON file that contains information about two propagated routes for VPC attachments.
