So....you're just looking for an easy way to number the lines? Powershell can do it easy peasy.
Code
$num = 0
$list = get-content C:\Users\q\Desktop\test.txt #<-full path to text file
foreach ($name in $list)
{
$num++
$name = "$num.) $name"
Write-Host $name
}
Open powershell, copy/paste that in, and it'll spit out the numbered names in the console and you can copy/paste it from there.
