Work with Live Amazon S3 Data in Power Query

Power Query is a data transformation and data preparation engine. When paired with CData Connect Cloud, you get instant, cloud-to-cloud access to Amazon S3 data from Power Query. This article shows how to connect to Connect Cloud from Power Query through Microsoft Excel and get live access to Amazon S3 data for transformation and preparation.

CData Connect Cloud provides a pure SQL, cloud-to-cloud interface for Amazon S3, allowing you to easily integrate with live Amazon S3 data in Power Query — without replicating the data. CData Connect Cloud looks exactly like a SQL Server database to Power Query and uses optimized data processing out of the box to push all supported SQL operations (filters, JOINs, etc) directly to Amazon S3, leveraging server-side processing to quickly return Amazon S3 data.

Configure Amazon S3 Connectivity for Power Query

Connectivity to Amazon S3 from Power Query is made possible through CData Connect Cloud. To work with Amazon S3 data from Power Query, we start by creating and configuring a Amazon S3 connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "Amazon S3" from the Add Connection panel
3. Enter the necessary authentication properties to connect to Amazon S3.

   To authorize Amazon S3 requests, provide the credentials for an administrator account or for an IAM user with custom permissions. Set AccessKey to the access key Id. Set SecretKey to the secret access key.

   Note: You can connect as the AWS account administrator, but it is recommended to use IAM user credentials to access AWS services.

   For information on obtaining the credentials and other authentication methods, refer to the Getting Started section of the Help documentation.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add Amazon S3 Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured, you are ready to connect to Amazon S3 data from Power Query.

1. In Microsoft Excel, open the Power Query Editor (from the Data ribbon, click Get Data -> Launch Power Query Editor)
2. Click New Source -> SQL Server
3. In the SQL Server database modal:
   • Set Server to tds.cdata.com,14333
   • (Optional) Set Database to the name of the Amazon S3 connection (e.g. AmazonS31 )
4. In the SQL Server credentials modal, select "Database" and
   • Set User to your Connect Cloud username (e.g. user@mydomain.com )
   • Set Password to the PAT for the above user
5. Click Connect
6. Select the table(s) you wish to work with in the Navigator and click "OK"

At this point, you have live access to Amazon S3 data from Power Query for transformation and preparation.
