You can also get data from an online source like Google Sheets, as long as the data is publicly available.
To import data from a URL, first you'll need to get a share URL from the data source. Open a document in Google Sheets and go to the File menu, select Share, then Publish to web. Make sure you choose Comma-separated values (.csv) in the second drop-down and hit Publish.
Copy the URL from Google and paste it into the dialog under URL in SmartDraw.
