Import Excel Online Data into Microsoft Power Query
The CData API Server offers standards-based Web service endpoints that allow a variety of applications to access Excel Online data. In this article, you will use the OData format to import Excel Online data into Microsoft Power Query.
The API Server, when paired with the ADO.NET Provider for Excel Online (or any of 200+ other ADO.NET Providers), enables you to use Web services to connect to and query Excel Online data. This article details how to import an OData feed of Excel Online data into Microsoft Power Query.
Set Up the API Server
Follow the steps below to begin producing secure Excel Online OData services:
Deploy
The API Server runs on your own server. On Windows, you can deploy using the stand-alone server or IIS. On a Java servlet container, drop in the API Server WAR file. See the help documentation for more information and how-tos.
The API Server is also easy to deploy on Microsoft Azure, Amazon EC2, and Heroku.
Connect to Excel Online
After you deploy the API Server and the ADO.NET Provider for Excel Online, provide authentication values and other connection properties needed to connect to Excel Online by clicking Settings -> Connections and adding a new connection in the API Server administration console.
You can connect to a workbook by providing authentication to Excel Online and then setting the following properties:
-
Workbook: Set this to the name or Id of the workbook.
If you want to view a list of information about the available workbooks, execute a query to the Workbooks view after you authenticate.
- UseSandbox: Set this to true if you are connecting to a workbook in a sandbox account. Otherwise, leave this blank to connect to a production account.
You use the OAuth authentication standard to authenticate to Excel Online. See the Getting Started section in the help documentation for a guide. Getting Started also guides you through executing SQL to worksheets and ranges.
You can then choose the Excel Online entities you want to allow the API Server access to by clicking Settings -> Resources.
Authorize API Server Users
After determining the OData services you want to produce, authorize users by clicking Settings -> Users. The API Server uses authtoken-based authentication and supports the major authentication schemes. Access can also be restricted based on IP address; by default, only connections to the local machine are allowed. You can authenticate as well as encrypt connections with SSL.
Connect to Excel Online Data from Power Query
Follow the steps below to import tables that can be refreshed on demand:
- Configure the API Server to use a version of the OData protocol that is recognized by Power Query. In the API Server administration console, click Settings -> Server and change the value of the Default Version property to 3.0.
-
From the ribbon in Excel, click Power Query -> From Other Data Sources -> From OData Feed, and enter the OData URL:
https://your-server:8032/api.rsc
-
In the next step of the wizard, define authentication credentials and set privacy levels. Select Basic authentication and enter the credentials for a user authorized to make requests. Specify the Username field and enter the user's authtoken in the Password field.
To change the authentication scheme that Power Query will use, click Power Query -> Data Source Settings. Select the OData feed from the list and then click Edit Credential. Select the privacy level from the menu on the Data Source Settings page.
-
You can now access Excel Online data in Power Query. In the Navigator expand the node for the OData feed, right-click a table, and click Edit to open the Query Editor. This will display the table data.
