Connect to Excel Online Data and Transfer Data in Talend

This article shows how you can easily integrate the CData JDBC driver for Excel Online into your workflow in Talend. This article uses the CData JDBC Driver for Excel Online to transfer Excel Online data in a job flow in Talend.

Connect to Excel Online in Talend as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to Excel Online:

1. Add a new database connection to Excel Online data: To add a new connection, expand the Metadata node, right-click the Db Connections node, and then click Create Connection.
2. In the resulting wizard, enter a name for the connection.

3. On the next page, select Generic JDBC from the DB Type menu and enter the JDBC URL.

   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.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.excelonline.jar

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

   A typical JDBC URL is below:

   jdbc:excelonline:InitiateOAuth=GETANDREFRESH
4. Enter the path to the cdata.jdbc.excelonline.jar file, located in the lib subfolder of the installation directory.
5. Right-click the connection and then click Retrieve Schema.
6. Click Next with the default options to select the tables you want to import.
7. Finish the wizard with the default options.

1. In the Table Schemas node, drag the tables to the workspace.
2. In the dialog that is displayed, select the tJDBCInput component.
3. Next, drag a tFileOutputDelimited component from the Business Intelligence tab of the Palette into the workspace.
4. Right-click the Test_xlsx_Sheet1 tJDBCInput component and drag a vector to the output file.
