windows - In Vim, what is the simplest way to join all lines in a file into a single line?

Question

I want to join all lines in a file into a single line. What is the simplest way of doing this? I've had poor luck trying to use substitution ( or doesn't seem to get picked up correctly in the case of s/ // on Windows). Using J in a range expression doesn't seem to work either (probably because the range is no longer in 'sync' after the first command is executed).

I tried :1,$norm! J but this only did half of the file - which makes sense because it just joins each line once.

Another way:

ggVGJ

"ggVG" visually selects all lines, and "J" joins them.
