Create data visualizations based on Elasticsearch data in Excel.

NOTE: For Excel for the web (Excel 365) and Excel 2019 or higher, Power View is no longer supported. Microsoft encourages the use of Power BI for those users. Please read our article on working with Elasticsearch in Power BI using our Power BI connector for more information.

You can use the built-in ODBC support in Excel to rapidly create Power View reports featuring Elasticsearch data. This article shows how to use the Data Connection Wizard, accessible from the Data ribbon, to import Elasticsearch data into a Power View report.

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.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

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 with the Data Connection Wizard

Follow the steps below to connect to the DSN from the Data Connection Wizard in Excel.

  1. In recent versions of Excel the Data Connection Wizard is not visible by default. To enable the Data Connection Wizard in Excel, go to File -> Options -> Data and under Show legacy data import wizards check the From Data Connection Wizard (Legacy).
  2. After enabling the Data Connection Wizard, on the Data tab you can click Get Data -> Legacy Wizards -> From Data Connection Wizard (Legacy).
  3. In the Data Connection Wizard, select the ODBC DSN option.
  4. Select the ODBC DSN for Elasticsearch from the list.

  5. Select the tables you want to work with.

    If you want to import multiple tables, deselect the "Connect to a specific table" option. After you connect to the data source, you can select multiple tables: After you click Finish to close the Data Connection Wizard, select the "Enable selection of multiple tables" option in the Select Table dialog.

  6. In the Import Data dialog, select the destination for your data. For example, select the Table option and the Existing worksheet option. Then click the cell in your worksheet where results should be output.
  7. Click Insert -> Power View to create a new Power View report.

Create a Table

Tables are the starting point for charts and other representations of your data. To create a table, select a column in the field list. You can also drag and drop table names and column names onto the view.

Create Data Visualizations

On the Design tab, you can change tables into charts and other visualizations.

Elasticsearch ODBC Driver

The Elasticsearch ODBC Driver is a powerful tool that allows you to connect with live Elasticsearch document databases, directly from any applications that support ODBC connectivity.

Access Elasticsearch like you would a database - read, write, and update through a standard ODBC Driver interface.
