Getting data and connector navigation
Power Query, thanks to its interface, offers an easy way to connect to data sources. In the previous chapter, you saw different authentication types, but here you will get an overview of the connector types and learn which one fits best. You will also learn the difference between preview (or beta) and general availability connectors.
Getting ready
For this recipe, you need to have Power BI Desktop running on your machine.
How to do it...
Open Power BI Desktop and you will be ready to perform the following steps:
- The first step in every version of the Power Query tool, whether it is the online or desktop version, is to click on Get data:
Figure 2.1 – Get data in Power Query Desktop (left) and Get data in Power Query online (right)
- Once you expand the Get data section, you will end up with the following view in the Power Query Desktop version:

And if you expand the same section in the Power Query online version, you will see the following:

Both versions have the following connectors divided into the same categories:
- File: You can connect to different types of files, such as Excel, CSV/TXT, XML, JSON, Folder, PDF, and Parquet.
- Database: You can connect to all mainstream databases such as Microsoft, Oracle, IBM, open source databases (MySQL, PostgreSQL, and MariaDB), Teradata, SAP, Amazon Redshift, Google BigQuery, Snowflake, and many others. This wide variety allows the user able to connect to the different sources and not have concerns about having the required data in only one standard data source.
- Power Platform: You can connect live to Power BI datasets already published in the Power BI service. You will have the ability to connect to already prepared and transformed queries with the Power BI dataflow connectors and perform additional steps without doing everything from scratch.
- Azure: You can connect to all Azure Data Services sources, such as Azure SQL Database, Azure Synapse, Azure Data Lake Storage, and to Azure open source services such as Azure Databricks and Azure HDInsight.
- Online Services: You can connect to a wide range of third-party services and use native connectors to the Dynamics platform, Salesforce, Google Analytics, and other services that are continuously updated and released.
- Other: This category collects more generic connectors, such as web connectors (used for getting data from websites, to make API calls, or to import files from the web), OData feeds, ODBC, and R and Python scripts. This set of connectors allows users to leverage some common connection logic that is used in other tools that can also be replicated with Power Query.
Users have to check what connectors are available in each version of Power Query – either the desktop or online version – and they have to research new connectors' availability. There are new ones both in beta (as shown in the following figure) and a general availability version with every release of Power Query. This list is constantly updated in the Microsoft documentation:
