Import MongoDB Data into Microsoft Power Query
The CData API Server offers standards-based Web service endpoints that allow a variety of applications to access MongoDB data. In this article, you will use the OData format to import MongoDB data into Microsoft Power Query.
The API Server, when paired with the ADO.NET Provider for MongoDB (or any of 200+ other ADO.NET Providers), enables you to use Web services to connect to and query MongoDB data. This article details how to import an OData feed of MongoDB data into Microsoft Power Query.
About MongoDB Data Integration
Accessing and integrating live data from MongoDB has never been easier with CData. Customers rely on CData connectivity to:
- Access data from MongoDB 2.6 and above, ensuring broad usability across various MongoDB versions.
- Easily manage unstructured data thanks to flexible NoSQL (learn more here: Leading-Edge Drivers for NoSQL Integration).
- Leverage feature advantages over other NoSQL drivers and realize functional benefits when working with MongoDB data (learn more here: A Feature Comparison of Drivers for NoSQL).
MongoDB's flexibility means that it can be used as a transactional, operational, or analytical database. That means CData customers use our solutions to integrate their business data with MongoDB or integrate their MongoDB data with their data warehouse (or both). Customers also leverage our live connectivity options to analyze and report on MongoDB directly from their preferred tools, like Power BI and Tableau.

Getting Started
Set Up the API Server
Follow the steps below to begin producing secure MongoDB 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 MongoDB
After you deploy the API Server and the ADO.NET Provider for MongoDB, provide authentication values and other connection properties needed to connect to MongoDB by clicking Settings -> Connections and adding a new connection in the API Server administration console.
Set the Server, Database, User, and Password connection properties to connect to MongoDB. To access MongoDB collections as tables you can use automatic schema discovery or write your own schema definitions. Schemas are defined in .rsd files, which have a simple format. You can also execute free-form queries that are not tied to the schema.
You can then choose the MongoDB 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 MongoDB 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 MongoDB 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.
