Here you go. If you don't have PDF converter installed,
1. Open Adobe Acrobat ver.8
2. Go to File - Save As
3. Choose 'All Files' option and besides the name of file add the extension .xls

If you have images try adding manually. You won't get the results you want and will have to arrange bit manually. This is the best you can do with Acrobat. Try with one file first. *Fingers Cross*.
