Need to convert postcodes into What3Words addresses? W3WConverter uses Google Places API to convert a postcode into latitude-longitude coordinates and then sends these to What3Words via their API to output a CSV file containing What3Words addresses.
You will need to create a .env file and set the following variables with your own API keys: GOOGLE_API_KEY and W3W_API_KEY.
npm install w3wconverter
const W3WConverter = require('w3wconverter');
...
const config = [];
config['fileToConvert'] = <path to file>;
config['fileToWrite'] = <filename without extension>;
const w3wconverter = new W3WConverter(config);
// Returns a Json type response that can be displayed in a webpage. Console also shows 'Done'
const result = w3wconverter.convertData();
