Hi @CFernandes
This is not strictly speaking a power automate solution. The PA flow just basically writes to a excel table in a standard way.
The groovy stuff is done in the Excel / powerpoint.
Excel.
Simply create master data sheet within a table for PA to access.
Create 1 / many other sheets that have the layout / images / etc you desire, and back ref to the data sheet as required. (This I did to create complex looking forms etc)
Powerpoint
Create a slide as required, I used combination of blank ones (Used entire layout from Excel) and detailed ones with specific fields only linked.
Open excel, highlight the cell / cells you with to have in powerpoint.
Powerpoint select Paste special.
Select Excel object.
Select link data
Paste in.
Once pasted in you can resize, move about as if it was a picture.
Save both files.
Now powerpoint will ask to update or not as it opens, do NOT have excel open when you do this. Say yes for first time. (Get a coffee) then save and say no until excel is reloaded with new data.
HTH
