Viewing Excel Data in RAD Studio Data Explorer
Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for Excel, you gain access to live Excel data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update Excel data. This article will walk through connecting to Excel using the Data Explorer.
Configure a Connection to Excel
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.
Connecting to Local or Cloud-Stored (Box, Google Drive, Amazon S3, SharePoint) Excel Files
CData Drivers let you work with Excel files stored locally and stored in cloud storage services like Box, Amazon S3, Google Drive, or SharePoint, right where they are.
Setting connection properties for local files
Set the URI property to local folder path.
Setting connection properties for files stored in Amazon S3
To connect to Excel file(s) within Amazon S3, set the URI property to the URI of the Bucket and Folder where the intended Excel files exist. In addition, at least set these properties:
- AWSAccessKey: AWS Access Key (username)
- AWSSecretKey: AWS Secret Key
Setting connection properties for files stored in Box
To connect to Excel file(s) within Box, set the URI property to the URI of the folder that includes the intended Excel file(s). Use the OAuth authentication method to connect to Box.
Dropbox
To connect to Excel file(s) within Dropbox, set the URI proprerty to the URI of the folder that includes the intended Excel file(s). Use the OAuth authentication method to connect to Dropbox. Either User Account or Service Account can be used to authenticate.
SharePoint Online (SOAP)
To connect to Excel file(s) within SharePoint with SOAP Schema, set the URI proprerty to the URI of the document library that includes the intended Excel file. Set User, Password, and StorageBaseURL.
SharePoint Online REST
To connect to Excel file(s) within SharePoint with REST Schema, set the URI proprerty to the URI of the document library that includes the intended Excel file. StorageBaseURL is optional. If not set, the driver will use the root drive. OAuth is used to authenticate.
Google Drive
To connect to Excel file(s) within Google Drive, set the URI property to the URI of the folder that includes the intended Excel file(s). Use the OAuth authentication method to connect and set InitiateOAuth to GETANDREFRESH.
Connecting to Excel Data Using Data Explorer
You can create a simple application for displaying Excel data by utilizing the CData FireDAC Components for Excel and a new VCL Forms Application:
- Open the Data Explorer in RAD Studio and expand FireDAC.
- Right-click the ODBC Data Source node in the Data Explorer.
- Click Add New Connection.

- Enter a name for the connection.
- In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for Excel.

- Back in the Data Explorer, expand the tables for the connection.
Create a new VCL Forms application and drag a table (for example: Sheet) onto the form.

- Select the SheetTable object on the form and set the Active property to true.
Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).

Arrange the TStringGrid on the form and run the application to see the Sheet data.
