Eliminate carriage returns (paragraph marks) at the end of each line but not at the end of each paragraph

1.

On the Edit Menu, choose Replace.

2.

In the Find What box, enter:

([!^13])(^13)([!^13])

In the Replace With box, enter:

\1 \3

Click the More.. button, and check “Use Wildcards”.

Click Replace All and click OK when Word tells you it has done the replacement.

This will remove any paragraph marks that are at the end of a line but within a paragraph.

3.

Now, in the Find What box, enter:

^13{2,}

In the Replace With box, enter:

^p

Click Replace All and click OK when Word tells you it has done the replacement.

This will remove multiple consecutive paragraph marks, so that each paragraph ends with just one paragraph mark, as it should. (But also see the article: Remove all empty paragraphs from a document.)

Note that the “Use Wildcards” setting is “sticky”, so if you subsequently do another Find and Replace during the same Word session, you have to remember to switch it off again, if appropriate. (Or see the article: Clear settings from Find and Replace dialog to prevent unexpected results from future Find or Replace operations.)
