Access Live Oracle Data in Excel 365 Online (Excel for the web)

Microsoft Excel for the web represents a cloud-native iteration of Microsoft Excel. When integrated with CData Connect Cloud, you gain immediate access to Oracle data directly from within Excel. This access facilitates data analysis, collaborative work, calculations, and more. This article provides a step-by-step guide on connecting to Oracle within your Connect Cloud instance and accessing live Oracle data in Excel for the web spreadsheets, whether for viewing or updating purposes.

CData Connect Cloud provides a pure cloud-to-cloud interface for Oracle, allowing you to easily access live Oracle data in Excel for the web. Simply use the Connect Cloud Add-In to query live data (or write your own). Using optimized data processing out of the box, CData Connect Cloud pushes all supported query operations (filters, JOINs, etc) directly to Oracle, leveraging server-side processing to quickly return Oracle data.

Configure Oracle Connectivity for Excel

Connectivity to Oracle from Excel is made possible through CData Connect Cloud. To work with Oracle data from Excel, we start by creating and configuring a Oracle connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "Oracle" from the Add Connection panel
3. Enter the necessary authentication properties to connect to Oracle.

   To connect to Oracle, you'll first need to update your PATH variable and ensure it contains a folder location that includes the native DLLs. The native DLLs can be found in the lib folder inside the installation directory. Once you've done this, set the following to connect:

   • Port: The port used to connect to the server hosting the Oracle database.
   • User: The user Id provided for authentication with the Oracle database.
   • Password: The password provided for authentication with the Oracle database.
   • Service Name: The service name of the Oracle database.
4. Click Create & Test
5. Navigate to the Permissions tab in the Add Oracle Connection page and update the User-based permissions.

With the connection configured, you are ready to connect to Oracle data from Excel for the web.
