How to connect to ADP Data from MS Excel on Mac OS X

Microsoft Excel features calculations, graphing tools, pivot tables, and a macro programming language that allows users to work with data in many of the ways that suit their needs, whether on a Windows machine or a Macintosh machine. This article walks through creating a DSN for ADP data in iODBC and accessing ADP data in Microsoft Excel, all on a machine running Mac OS X.

Installing the CData ODBC Drivers on Mac OS X

The CData ODBC Driver for ADP is preconfigured for the iODBC driver manager, as are many other products like Microsoft Excel. This makes the driver easy to use with these tools.

Licensing the Driver

In a terminal run the following commands to license the driver. To activate a trial license, omit the key input.

cd "/Applications/CData ODBC Driver for ADP/bin"
sudo ./install-license <key>

Defining a DSN for iODBC with odbc.ini

You can define ODBC data sources in sections in the odbc.ini file. User data sources can only be accessed by the user account whose home folder the odbc.ini is located in. System data sources can be accessed by all users. You can find the correct odbc.ini in the following paths:

Modifying iODBC's system-wide settings requires elevated permissions; to do so, you can use following to open a text editor from the terminal:

sudo nano /Library/ODBC/odbc.ini

Connect to ADP by specifying the following properties:

• SSLClientCert: Set this to the certificate provided during registration.
• SSLClientCertPassword: Set this to the password of the certificate.
• UseUAT: The connector makes requests to the production environment by default. If using a developer account, set UseUAT = true.
• RowScanDepth: The maximum number of rows to scan for the custom fields columns available in the table. The default value will be set to 100. Setting a high value may decrease performance.

The connector uses OAuth to authenticate with ADP. OAuth requires the authenticating user to interact with ADP using the browser. For more information, refer to the OAuth section in the Help documentation.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

In addition to the connection properties required to connect to ADP, the Driver property specifies either a driver definition in the odbcinst.ini file or the path to the driver library. Place your connection properties at the beginning of odbc.ini:

[CData ADP Sources]
Driver = CData ODBC Driver for ADP
OAuthClientId = YourClientId
OAuthClientSecret = YourClientSecret
SSLClientCert = 'c:\cert.pfx'
SSLClientCertPassword = 'admin@123'

If you wish to authenticate using OAuth, you will need to add an additional connection property to ensure that the OAuth flow can execute properly:

Other = CheckPromptMode=False

Mac OS validates our drivers separately so you need to copy the license file to the appropriate path as well. After you have configured odbc.ini, run the following command.

sudo cp /Applications/CData ODBC Driver for ADP/lib/CData.ODBC.ADP.lic /Users/<YOUR_USER>/Library/Containers/com.microsoft.Excel/Data/.cdata/

Additionally, in the ODBC Data Sources section, the DSN must be set to a driver defined in the odbcinst.ini file. For example, below is the entry for the DSN created during the driver install:

[ODBC Data Sources]
CData ADP Source = CData ODBC Driver for ADP

Registering a DSN for iODBC with odbcinst.ini

You may need to modify the installed driver definition if you change the path to the driver library. To register an ODBC driver, modify the odbcinst.ini file. With iODBC, drivers can be available to only one user account or drivers can be available system wide. You can find the correct odbcinst.ini in the following paths:

Drivers are defined in sections in the odbcinst.ini file. The section name specifies the name of the driver. In this section, the Driver property specifies the path to the driver library. The driver library is the .dylib file located in the lib subfolder of the installation directory, by default in /Applications/CData ODBC Driver for ADP.

[CData ODBC Driver for ADP]
Driver = /Applications/CData ODBC Driver for ADP/lib/libadp.odbc.dylib

The ODBC Drivers section must also contain a property with the driver name, set to "Installed".

[ODBC Drivers]
CData ODBC Driver for ADP = Installed

Testing the Connection

You can test your connection using the iODBC administrator.

1. Open a terminal and enter the following command to start the iODBC Administrator with the necessary permissions:

   sudo /Applications/iODBC/iODBC\ Administrator64.app/Contents/MacOS/iODBC\ Administrator64
   

2. On the Users tab, select CData ADP Source.
3. Click the Test button.

Accessing ADP Data from Microsoft Excel

You can use the DSN configured above to access ADP data from Microsoft Excel.

1. Open Microsoft Excel and open a spreadsheet (new or existing).
2. Navigate to the data ribbon and select New Database Query From Database
3. Select the User or System DSN that you previously configured and click OK.
4. Build your SQL query in the Microsoft Query wizard:
5. Click Return Data to execute the query and pull data into Excel.

Using the CData ODBC Driver for ADP, you can easily pull your ADP data directly into Excel. Once there, you can leverage all of the powerful features native to Excel to analyze, report, transform your ADP data, and more!
