Looking for working Monster/NPC importer.

I am looking to make a lot of NPCs in this case for DnD 5e. Is there a script that will fill out the NPC sheet? At the very least with the basics? 

Where is the data to be imported coming from? What format is the data in?  Mod scripts can be used to import data into the D&D 5E by Roll20 character sheet, but the data and commands have to be formatted correctly for it to work.  An example of a script that can set attributes is ChatSetAttr. You wouldn’t be able to add information to the Bio tab, or add a default token or image with that script though. Other scripts could do that. 

I'll check that one out. Thank you. The ones I have tried said to put the info in the GM Token bio. But never seem to work. But they are also years old.
