In Power BI, adding a data source means connecting to a file, database, service, or online source where your data lives. Here’s how:
- Make sure you're on the 'Home' tab when you launch it. Click the 'Get Data' button.
- Choose your data source.
- After choosing your source, Power BI will prompt you to add a file. Choose the file and click 'Open'.
- Select the table you want to import and click 'Load'.
- Once connected, you can pull the data into Power BI and start building visuals.
