Using DistanceMatrixService within Google Apps Script - google-maps-api-3

Question

From a GAS, is it possible to call Maps API services such as DistanceMatrix?
I'd like to calculate distance between addresses stored in a spreadsheet.
I suppose displaying a map is required, to comply with terms of the Maps API.
Would something like the following be possible?
var service = new Maps.DistanceMatrixService();
service.getDistanceMatrix(
{
origins: [OAddresses],
destinations: [DAddresses],
travelMode: Maps.TravelMode.DRIVING,
unitSystem: Maps.UnitSystem.METRIC,
avoidHighways: false,
avoidTolls: false
}, callback);

Answer 1

This will help you..It is the complete code with file parsing.
It skips 1st row because of headings.
please change "sheet name" according to your need.
Check the screenshot for better understanding.

function geoDistance() {
var sheetName = 'xyz';
var activeSpreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var selectedSheet = activeSpreadsheet.getSheetByName(sheetName);
var sheet = selectedSheet;
var lastRow = sheet.getLastRow();
var N = lastRow;
for (var i=2;i<=N;i++){
var startpoint = sheet.getRange(i, 1, 1, 1).getValue();
var endpoint = sheet.getRange(i, 2, 1, 1).getValue();
var directions = Maps.newDirectionFinder()
.setOrigin(startpoint)
.setDestination(endpoint)
.setMode(Maps.DirectionFinder.Mode.DRIVING)
.getDirections();
var print = sheet.getRange(i,3,1,1).setValue(directions.routes[0].legs[0].distance.text);
}}
