Find & Replace Powerpoint Text from Excel

I am completely lost trying to write this macro. I am trying to use the Powerpoint.Application object to access an existing presentation and search through all slides for text "xxxx" and replace with text from a cell in excel. I am able to do this using excel and word but am completely stumped when it comes to excel and powerpoint. I see a lot of examples out there of a macro within powerpoint, but I can't seem to find any help regarding accomplishing it through excel. The general gist of it should be to search through all slides, all shapes within each slide for text ranges that contain the string "xxxx"


Thanks in advance!

Can anyone help with this problem that I am also having.

I can not believe that there is no FInd and Replace code for PowerPoint

Please can anyone help?!
