Can I export data from a dashboard to Excel?

First of all, you need to export data to CSV. 

See 

Once you have downloaded the CSV file,

• Open an existing Excel workbook or create a new one.
• Click on the Data tab.
• Click on the From Text/CSV button.

• Select the CSV file in the file selector prompt that just opened.

• Review the data and click on Load.

To choose where to input the CSV data in your workbook, click on the arrow at the right of the Load button and select Load to.
