I think the answer is yes, depending on the design of your spreadsheet.
It is always an adventure in data format conversion when using the
clipboard between apps.
When I have done this using Applescript and other programs (LC, etc.)
exchanging with Excel...
I write the spreadsheet formulas to 'gather' all the values into one
cell using a series of formulas, then copy that single cell.
As a better practice, I name the cell, and access it by name rather
than cell address.
Using the formulated value allows you to choose your delimiters
(such as char 160 = CR, and char 161 = tab )
and avoid the variations with tab, return cross platform.
This means the same Excel formula and the same LC handler will work on
all versions of Win, Mac, and incarnations of Excel.
I have used this approach for very large text runs, in particular,
merging (html + values) to create complete web pages in a single cell.
Also, when switching between apps using the clipboard, be aware that
you should do an Applescript line such as
tell app "Microsoft Excel"
-- copy named cell
delay 1 -- wait 1 second
tell app "Livecode" to activate --
put the clipboarddata into tTextBlock
--now parse delims ( 161, 160 )
This gives each app time to convert the clipboard, especially if it is
