Combine ListEntries in memory and Convert ListFeed to a CellFeed

[David Hodge]

I want to get x number of worksheets in different spreadsheets, combine the 
entries and sort on a certain column and loop thru each cell and perform 
some logic.  What is the best way to do this?

I want to know if it is possible to:

1) Combine ListEntries from multiple worksheets in memory
2) Convert a ListFeed to a CellFeed

Regards,

Dave
