Taking data from an Outlook attachment & dumping into Excel via a macro & adding to it?

Okay, major newbie to Outlook macros and best a 1st grade level to writing macros in Excel. This what I would like to do:
I receive three emails once a month with at least 13K of lines in them, I would like the first one to automatically open in Excel and paste data into a new workbook or master workbook (gonna have to use powerpivot or pivot tables once I have all data into a worksheet) then it would open the second email and paste the data into the first blank row in that new worksheet and/or master file (aka data dump), and then lastly the third email would do the same thing as the second one.

So is this possible for someone like me who is basically cutting her teeth on how to do macros in Outlook & Excel?
Thanks in advance for any guidance on this

bump, I really need help on this..TIA!
