How do I remove the blank spaces before a certain character using notepad++

Solution 1:

The easiest way (but probably not bullet proof is Find&Replace

Search for .V and replace with .V and tick match case for certain cases you may even search (from your examples given) for .V to get better hits

Solution 2:

If there is only one space before the .V, then using @alfetta's answer is the way to go. If there are one or more spaces before it, then you can try the following:

  • Find what : \s+(\.V)
  • Replace with : $1
  • Search mode : Regular expression
