Excel Services JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with live Excel Spreadsheet content hosted on SharePoint server!

Access and process Excel Services Data in Apache Spark using the CData JDBC Driver.

Apache Spark is a fast and general engine for large-scale data processing. When paired with the CData JDBC Driver for Excel Services, Spark can work with live Excel Services data. This article describes how to connect to and query Excel Services data from a Spark shell.

The CData JDBC Driver offers unmatched performance for interacting with live Excel Services data due to optimized data processing built into the driver. When you issue complex SQL queries to Excel Services, the driver pushes supported SQL operations, like filters and aggregations, directly to Excel Services and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can work with and analyze Excel Services data using native data types.

Install the CData JDBC Driver for Excel Services

Download the CData JDBC Driver for Excel Services installer, unzip the package, and run the JAR file to install the driver.

Start a Spark Shell and Connect to Excel Services Data

  1. Open a terminal and start the Spark shell with the CData JDBC Driver for Excel Services JAR file as the jars parameter: $ spark-shell --jars /CData/CData JDBC Driver for Excel Services/lib/cdata.jdbc.excelservices.jar
  2. With the shell running, you can connect to Excel Services with a JDBC URL and use the SQL Context load() function to read a table.

    The URL, User, and Password properties, under the Authentication section, must be set to valid credentials for SharePoint Online, SharePoint 2010, or SharePoint 2013. Additionally, the Library property must be set to a valid SharePoint Document Library and the File property must be set to a valid .xlsx file in the indicated Library.

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the Excel Services JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.excelservices.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    Configure the connection to Excel Services, using the connection string generated above.

    scala> val excelservices_df ="jdbc").option("url", "jdbc:excelservices:URL=;;Password=password;File=Book1.xlsx;").option("dbtable","Account").option("driver","cdata.jdbc.excelservices.ExcelServicesDriver").load()
  3. Once you connect and the data is loaded you will see the table schema displayed.
  4. Register the Excel Services data as a temporary table:

    scala> excelservices_df.registerTable("account")
  5. Perform custom SQL queries against the Data using commands like the one below:

    scala> excelservices_df.sqlContext.sql("SELECT Name, AnnualRevenue FROM Account WHERE Industry = Floppy Disks").collect.foreach(println)

    You will see the results displayed in the console, similar to the following:
