Connect to Excel Online Data in CloverETL

Transfer Excel Online data using the visual workflow in the CloverETL data integration tool.

The CData JDBC Driver for Excel Online enables you to use the data transformation components in CloverETL to execute create, read, update, and delete (CRUD) commands to Excel Online data. In this article, you will use the JDBC Driver for Excel Online to set up a simple transfer into a flat file.

Connect to Excel Online as a JDBC Data Source

  1. Create the connection to Excel Online data. In a new CloverETL graph, right-click the Connections node in the Outline pane and click Connections -> Create Connection. The Database Connection wizard is displayed.
  2. Click the plus icon to load a driver from a JAR. Browse to the lib subfolder of the installation directory and select the cdata.jdbc.excelonline.jar file.
  3. Enter the JDBC URL. A typical JDBC URL is below: jdbc:excelonline:

    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.

Query Excel Online Data with the DBInputTable Component

  1. Drag a DBInputTable from the Readers selection of the Palette onto the job flow and double-click it to open the configuration editor.
  2. In the DB connection property, select the Excel Online JDBC data source from the drop-down menu.
  3. Enter the SQL query. For example: SELECT * FROM Test_xlsx_Sheet1

Write the Output of the Query to a UniversalDataWriter

  1. Drag a UniversalDataWriter from the Writers selection onto the jobflow.
  2. Double-click the UniversalDataWriter to open the configuration editor and add a file URL.
  3. Right-click the DBInputTable and then click Extract Metadata.
  4. Connect the output port of the DBInputTable to the UniversalDataWriter.
  5. In the resulting Select Metadata menu for the UniversalDataWriter, choose the Test_xlsx_Sheet1 table. (You can also open this menu by right-clicking the input port for the UniversalDataWriter.)
  6. Click Run to write to the file.
