Sure thing,
In word open the Find and Replace tool. (Ctrl + H)
In the find field put a ^w (that signifies whitespace)
Leave the replace field blank then click find all or find if you want to go line by line.

EDIT: Are there two spaces between the words?
The problem is telling MS word to delete spaces, but not the spaces between words.
What I would do is make a macro that actually runs three different search and replace.
Again this all depends on there being 2 spaces between each word, yet one space between each letter.
Ctrl + H (find and replace)
Search for " " (that's a space space)
Replace with "+++" (anything arbitrary will work here)
then
Search for " " (one space)
Replace with (that's a blank)
then
Search for "+++" (the arbitrary replacement)
Replace with " " (one space)
You should be left with the spacing correct between words and the spaces gone from between the letters.
