Tableau provides various options to export data from a worksheet. The formats available are typically those that are best suited for visualization or further data analysis. The options include:

.png for exporting images of the visualizations
.xlsx for exporting data in a format that can be opened with Microsoft Excel
.pptx for creating PowerPoint presentations with the visualization embedded

These formats are designed to facilitate sharing and presenting the insights derived from Tableau visualizations, or for conducting further analysis in tools like Excel.
