Welcome to the Oracle Analytics and AI community and forum.
You maybe forgot to write the question as there is just a title.
Guessing what you wanted to ask, DV export to Excel is only for tables and pivots. Other visualizations are limited to pdf, PowerPoint, images or csv.
If you want to ask for the feature to be able to export DV workbooks visualization to Excel files, you can look for an existing idea asking the same in https://community.oracle.com/products/oracleanalytics/categories/idealab-oracle-analytics-cloud-server and upvote it. Or if there isn't an idea for it already (quite sure it should exist), you can post it as a new idea.
