Note: If pulled from polutils, you must first convert the old-style id to decimal first before using it with this or it wont work
New-style (3 digit) to old-style:
New style NPC ID in first box
NPC's ZoneID in second box
Click 'Generate'
Old-style to new-style:
Old-style NPC ID in last box
NPC's ZoneID in ZoneID box
Click 'Reverse it!' (Yes that was the best name i could think of)
First attempt at creating a 'program' so apologies if i screwed up (my code sucks).
