Use the CData ODBC Driver for Alchemy in Microsoft Power Query

The CData ODBC Driver for Alchemy enables you to link to Alchemy data in Microsoft Power Query, ensuring that you see any updates. This article details how to use the ODBC driver to import Alchemy data into Microsoft Power Query.

Connect to Alchemy 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.

Start by setting the Profile connection property to the location of the Alchemy Profile on disk (e.g. C:\profiles\Alchemy.apip). Next, set the ProfileSettings connection property to the connection string for Alchemy (see below).

Alchemy API Profile Settings

Alchemy uses API key authentication. The API key is supplied in the request URL path. To obtain an API key:

1. Sign in to your Alchemy account at https://dashboard.alchemy.com.
2. Open an existing app or create a new one.
3. Copy the app's API key from the API Key dialog.

After obtaining your API key, set the following connection properties:

• AuthScheme: Set this to APIKey.
• Network: Optional. The blockchain network slug for NFT API requests (for example, eth-mainnet, base-mainnet, polygon-mainnet). Defaults to eth-mainnet.

Set the following in the ProfileSettings connection property:

• APIKey: Set this to your Alchemy app API key.

Import Alchemy Data

Follow the steps below to import Alchemy data using standard SQL:

1. From the ribbon in Excel, click Power Query -> From Other Data Sources -> From ODBC.

2. Enter the ODBC connection string. Below is a connection string using the default DSN created when you install the driver:

   Provider=MSDASQL.1;Persist Security Info=False;DSN=CData API Source

3. Enter the SELECT statement to import data with. For example:

   
       SELECT Address, Name FROM ContractsForOwner WHERE Owner = '0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045'
       

   

4. Enter credentials, if required, and click Connect. The results of the query are displayed in the Query Editor Preview. You can combine queries from other data sources or refine the data with Power Query formulas. To load the query to the worksheet, click the Close and Load button.
