You can use the CData Elasticsearch ODBC Driver with Microsoft Power Query. In this article, you will use the ODBC driver to import Elasticsearch data into Microsoft Power Query.

The CData ODBC Driver for Elasticsearch enables you to link to Elasticsearch data in Microsoft Power Query, ensuring that you see any updates. This article details how to use the ODBC driver to import Elasticsearch data into Microsoft Power Query.

About Elasticsearch Data Integration

Accessing and integrating live data from Elasticsearch has never been easier with CData. Customers rely on CData connectivity to:

  • Access both the SQL endpoints and REST endpoints, optimizing connectivity and offering more options when it comes to reading and writing Elasticsearch data.
  • Connect to virtually every Elasticsearch instance starting with v2.2 and Open Source Elasticsearch subscriptions.
  • Always receive a relevance score for the query results without explicitly requiring the SCORE() function, simplifying access from 3rd party tools and easily seeing how the query results rank in text relevance.
  • Search through multiple indices, relying on Elasticsearch to manage and process the query and results instead of the client machine.

Users frequently integrate Elasticsearch data with analytics tools such as Crystal Reports, Power BI, and Excel, and leverage our tools to enable a single, federated access layer to all of their data sources, including Elasticsearch.

Getting Started


Connect to Elasticsearch as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Set the Server and Port connection properties to connect. To authenticate, set the User and Password properties, PKI (public key infrastructure) properties, or both. To use PKI, set the SSLClientCert, SSLClientCertType, SSLClientCertSubject, and SSLClientCertPassword properties.

The data provider uses X-Pack Security for TLS/SSL and authentication. To connect over TLS/SSL, prefix the Server value with 'https://'. Note: TLS/SSL and client authentication must be enabled on X-Pack to use PKI.

Once the data provider is connected, X-Pack will then perform user authentication and grant role permissions based on the realms you have configured.

Import Elasticsearch Data

Follow the steps below to import Elasticsearch data using standard SQL:

  1. From the ribbon in Excel, click Power Query -> From Other Data Sources -> From ODBC.

  2. Enter the ODBC connection string. Below is a connection string using the default DSN created when you install the driver: 
    Provider=MSDASQL.1;Persist Security Info=False;DSN=CData Elasticsearch Source

  3. Enter the SELECT statement to import data with. For example: 

     SELECT Orders.Freight, Customers.ContactName FROM Customers INNER JOIN Orders ON Customers.CustomerId=Orders.CustomerId
    👁 The ODBC connection string and SELECT query. (Salesforce is shown.)

  4. Enter credentials, if required, and click Connect. The results of the query are displayed in the Query Editor Preview. You can combine queries from other data sources or refine the data with Power Query formulas. To load the query to the worksheet, click the Close and Load button.
