Macro with IF statement

I am very new to Word Macros.
I need a macro that will help clean up word files that have been badly formatted or converted.
Bascially I need a macro that will do this:
If a ¶ is present and not preceeded by a full stop, then delete that ¶ and replace with a single space.
The problem is that I have many files where paragraphs are split into several paragraphs. By deleting ¶ (and replacing with a single space) when it doesn't follow a full stop I hope that these broken paragraphs can be put together.
Any help much appreciated.
