If you are going from WORD to EXCEL - then to get everything to work
correctly - put you stuff into a WORD Table, then remove any of the
following with the find and replace function of WORD:
Remove all "paragraph marks" (^p), "manual line breaks" (^l), any "tabs
inside a cell" (^t). Then you should be able to paste into excel without
any problems.
You might have to "turn-on" non printing characters to be able to "see"
the tab, paragraph, and manual line breaks indicators. Also you can find
the above characters in the "FIND" popup menu - Select "MORE" tab - then
"SPECIAL." Then for the replace - just press the spacebar and this will
give you 1 space.

Going from EXCEL to WORD you should be able to do a COPY and PASTE.
