Problem
When exporting data, you only get options for PPT or PNG.
Solution
To export the visuals of a dashboard (look, feel and layout, especially if you have charts), use the export option on the preview dashboard menu.
Exporting the Data
There are two ways you can export information:
Export the Dashboard/Report: Use the export button (shown below) to export the dashboard or report itself. This option gives you two export formats.
Export the underlying data: If you want the data behind a report (for example, a data table), use the export icon in the top-right corner of the component. See the linked article for details on this process.
Note: The export button shown here only applies to dashboards and reports. Exporting the data behind them is a separate process with different format options.
