Add the MongoDB ODBC 1.0 Unicode Driver by clicking the ‘Add button’:
You can now see the MongoDB ODBC Data Source Configuration Use the server and port information from the mongodsql terminal as shown below:
No we are almost ready, Open Power BI. Click on ‘Get Data’ and scroll down to ODBC and select the data source we created in the previous steps:
