TESTING INSTRUCTIONS

1. Create a sample dataset. Refer to this sample dataset that I had created for testing.
2. Create a pivot table from the dataset. Refer attached screenshot above for reference.
3. Add the pivot table to a dashboard.
4. Click on the Download option in the dashboard and check if the Export to .Pivoted CSV option is available.
5. Click on the Export to .Pivoted CSV option and check if the file is downloaded in the .pivoted.csv format.
6. Open the downloaded file and check if the data is displayed correctly. For the sample dataset, the data should be displayed as shown below:

The pivot table was created as -

1. Columns - color
2. Rows - region
3. Metrics - COUNT(*)

As per this the downloaded data is as expected.

Tested out in the ephemeral and confirmed that this functions as intended. Code looks clean and straightforward to me.
