Use the CData ODBC Driver for Hugging Face from SharePoint Excel Services

The CData ODBC Driver for Hugging Face can be accessed using the built-in data access tools in Excel. This article demonstrates how to use the CData ODBC Driver for Hugging Face to connect to Hugging Face data from Excel spreadsheets in on-premises editions of SharePoint.

Connect to Hugging Face as an ODBC Data Source

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.

HuggingFace Hub uses token-based authentication to enable access to its API. The API provides access to machine learning models, datasets, spaces, papers, and other resources on the HuggingFace Hub platform.

Using API Key Authentication

To authenticate to HuggingFace Hub, you will need to provide an API Key (Access Token). To obtain your access token:

1. Log in to your HuggingFace account at https://huggingface.co
2. Navigate to Settings > Access Tokens
3. Click "New token" to create a new access token
4. Select the appropriate permissions (read or write)
5. Copy the token value

After obtaining your access token, set the following connection properties:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your HuggingFace access token.

Example connection string

Profile=C:\profiles\HuggingFace.apip;ProfileSettings='APIKey=hf_xxxxxxxxxxxxxxxxxxxx';

Configure Excel Services

Once the ODBC DSN is configured, you can configure Excel Services to use the DSN to connect. To do this, you will need to set up the OLE DB provider as a trusted data source. You will also want to decide if you want to use a Secure Store Service to enable single sign-on functionality with the ODBC driver. If you prefer, you can use the Excel Services Unattended account and skip to step 3 below.

1. First, set up a secure store application to use single sign-on. In SharePoint Central Administration, go to Application Management -> Manage Service Applications. Select your secure store service application or create a new one. Click Manage on the Edit menu to begin editing the application.
2. Create a new target application. You will be able to set the list of users who have access to this application. After the application is created, you will need to set the credentials on the application so that you can use this later for single sign-on.
3. Navigate to Application Management -> Manage Service Applications in SharePoint Central Administration. Select the Excel Services application used by your organization or create one if it does not already exist. Click Manage. If you create a new app, check the option to add the service application's proxy to the farm's default proxy list.
4. Click on Trusted Data Providers and add a new trusted provider. Set 'MSDASQL.1' for the Provider ID and leave the type as 'OLE DB'. Click OK to add this new provider to the list of trusted providers.

Connect to and Import Hugging Face Data in Excel

After you have enabled and secured access to the DSN, you can access the data source from the ribbon in Excel.

1. In an Excel spreadsheet, open the Data tab and click From Other Sources -> From Data Connection Wizard.
2. Select 'Other/Advanced' for the type and on the next screen, select the 'Microsoft OLE DB Provider for ODBC Drivers'. On the Connection tab, select CData API Sys, the system DSN. The driver installation automatically creates matching user and system DSNs: The system DSN is needed to connect from SharePoint.
3. Select the table you would like to connect to.
4. On the last step of the wizard, click the 'Authentication Settings' button. Select the 'Use a stored account' and enter the name of the secure store target application you created earlier. Or, if you want to use the Unattended Service Account, select None.
5. After you finish the wizard, the data is imported into the spreadsheet. You can now update and save Hugging Face data directly in SharePoint.
