Wynntils waypoint import converter

convert-waypoints.js

/*
USAGE:
Do to http://wynnwaypoints.tk/ and look for the download "For Xaero's Map".
Extract the .zip and find a text file with a name like "mw4,0,5_1.txt".
I suggest renaming it to something sane like "waypoint-data.txt".
Then run `node convert-waypoints.js waypoint-data.txt`.
This script will convert the waypoints
into a json format in a file "waypoint-data.txt_converted.json".
Take the copy the contents of this file and paste them into
the text field of this other converter: https://mitalashok.github.io/wynn-waypoints
This will output a string that you can then import into Wynntils through the clipboard.

If you don't have NodeJS installed, you can do so here: https://github.com/nvm-sh/nvm
Or run it online here: https://repl.it/@douira100/wynntils-waypoint-converter
