I have a 14 page word document and I want to add an 11 page excell
document to it. There must be an easy way. It is necessary that the
spreadsheet stay in the same format. Some of the Spreadsheets are
Portrait and some are Landscape.

Place your cursor at the last part of the page where you want to
format the page setup differently.
Select Format / Page Setup
Select Landscape and then change the Apply To Option to "This point
forward".  Then when you want to change back to Portrait do the same
thing... from this point forwad.  To insert the excel document select
Insert File and choose the document.  If there is enough room it will
be formatted the same.  Some find it is easier to just copy the cells
and past them where they want between the section breaks.  Hope this
helps.  kauaiDawn
