Use the CData ODBC Driver for Parquet in Microsoft Power Query

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

Connect to Parquet 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.

Connect to your local Parquet file(s) by setting the URI connection property to the location of the Parquet file.

Import Parquet Data

Follow the steps below to import Parquet 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 Parquet Source

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

    SELECT Id, Column1 FROM SampleTable_1 WHERE Column2 = 'SAMPLE_VALUE'

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.
