How To Remove Spaces Between Lines On Microsoft Word

This depends on whether those are really empty lines or your line spacing is set to 2. Try this (with Word XP (2002) and the adjacent versions. Word Vista probably has something similar): 

1. Select all the text with CTRL/A. 
2. Right-click in the text and select Paragraph. 
3. Under Spacing, make sure Before and After have zeroes and Line Spacing has "Single" with At blank. 
4. Click OK. 

If this fixes your problem, your spacing was double spacing. If it doesn't fix the problem, do this: 

1. On the menu bar, click the button that looks like ¶. This will turn on hidden formatting characters. The ¶'s that appear show the ends of each paragraph. If there are extras between your lines, you can do a mass delete them this way: 
2. Press CTRL/H to bring up the Find and Replace dialog box. 
3. In the Find what, put ^p^p 
This represents two adjacent paragraph marks. 
4. In the Replace With, put a single ^p 
5. Click the Replace All button. 

6. Click the ¶ button again to turn off the hidden characters.
