Are Microsoft Word and Excel interchangeable?
No they are not interchangeable. There are things that both can
do, but Microsoft Word is a word processor and Microsoft Excel is
an electronic spreadsheet. So they are both designed for different
kinds of jobs. You can copy things between one and the other, like
if you have a report in Word, and wanted to include some figures
from Excel. Microsoft Word is for working with text and Microsoft
Excel is for doing large scale calculations and other numerical
analysis and manipulation.
