Hey @mstoler I tested out a workflow and it seems to work!
You can read in the PPT as a Blob and then output directly the Blob using the name "output.pptx"
The excel is simple enough as well, you can have an input routed directly to an output with the same full file path of "output.xlsx|||<sheet name>
Attached is an example, let me know if this works!
Btw, the name of the file will have to be "output.fileextension" no other path for it to render for download in gallery I believe.
