ppt to excel

Alright,
I'm trying to take a powerpoint presentation and bring it into excel. The purpose being to compile all the data and be able to bounce formulas off multiple presentations once they have been pulled over.

I have pre-determined cells and sheets for the different slides. What I ultimately want is slide one to go to sheet one in a given range, Slide two to go to sheet two, three to three, four to four, five to five, and finally all slides to a compiled sheet 6.

I have the exact opposite of this project where I can build in excel and export to a ppt presentation but now I want the opposite. Here's what I have so far but I am wholly unfamiliar with VBA commands for ppt slides:

Code:

---

Option Explicit
Sub Opposite_Day()
Dim exlApp As Excel.Application
Dim exlbook As Excel.Workbook
Dim exlsheet As Worksheet

Set exlApp = New Excel.Application
exlApp.Visible = True
exlApp.Workbooks.Add
set exlsheet = Sheets.Add

End Sub

---

Any solutions on this one?
