How to create an RPA flow for Hugging Face Data in UiPath Studio

UiPath is a Robotic Process Automation (RPA) platform with rich features and an easy-to-use UI that enables non-developers to create process automation. By using UiPath Studio, you can build an RPA program just like drawing a diagram. With the CData API Driver for ODBC, users can embed Hugging Face data in the workflow.

This article explains how to use the Hugging Face ODBC Driver in UiPath Studio to create an RPA program that accesses Hugging Face data.

👁 Using the CData ODBC Data Sources in UiPath

Configure the Connection to Hugging Face

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';

Connect UiPath Studio to Hugging Face Data

Now you are ready to use Hugging Face data ODBC DSN in UiPath Studio with the following steps.

1. From the Start page, click Blank to create a New Project.
2. Click Manage Packages then search for and install UiPath.Database.Activities.
3. Navigate to the Activities and drop a Flowchart (Workflow -> Flowchart -> Flowchart) onto the process.
4. Drop a database Connect activity (App Integration -> Datbase -> Connect) after the Start activity.
5. Double-click the Connect activity and configure the Connection. 👁 Configure the Connect Activity
   
   1. Click the Connection Wizard
   2. Select "Microsoft ODBC Data Source"
   3. In Connection Properties, select your DSN (CData API Source) and click OK
6. To store Connection info, create a variable and bind to Output in the Properties section. Choose DatabaseConnection in Output.
   👁 Bind the Connection to the Output property.
   

Create an Execute Query Activity

With the connection configured, we are ready to query Hugging Face data in our RPA.

1. From the Activities navigation, select Execute Query and drop it on the Flowchart.
2. Double-click the Execute Query activity and set the properties as follows:
   • ExistingDbConnection: Your Connection variable
   • Sql: SELECT statement like SELECT , FROM Collections WHERE = ''
   • DataTable: Create and use a variable with the Type System.Data.DataTable
   👁 Set the Query for the ODBC Driver.
   

Create Write CSV Activity

With the Connection and Execute Query activities configured, we are ready to add a Write CSV activity to the Flowchart to replicate the Hugging Face data.

1. From the Activities navigation, select Write CSV and drop it after the Execute Query activity.
2. Double-click the Write CSV activity and set the properties as follows:
   • FilePath: Set to a file (new or existing) on disk (i.e.: C:\UiPath[id]-data.csv
   • DataTable: Set to the DataTable variable you created earlier

Connect the Activities and Run the Flowchart

If they are not already connected, connect each Activity that you created to complete the RPA project for extracting Hugging Face data and exporting it to CSV.

👁 Connect each Activity in the Flowchart

Click Run to extract Hugging Face data and create a CSV file.
