Spreadsheet Sorcery

maptimeLEX | November 18, 2015

What are we doing?

  • Load data from a Google Spreadsheet (SheetseeJS)
  • Transform that data into GeoJSON (SheeetseeJS)
  • Map the data (mapboxJS/LeafletJS)
  • Create a table of from our Google Spreadsheet data (SheetseeJS)
  • Add some interactivity driven by our data (SheetseeJS, MoustacheJS, ICanHazJS)

Final Map

A brief refresher

Webmap have:

Webmap have:

Basemap, tile layer, base layer, reference layer, etc.

Webmap have:

Feature data, feature layer, data layer, etc.

Which come together...

Let's make this map!

What you'll need

  • Text editor (Sublime, Notepad++, Komodo, etc)
  • Something to run a local web server
    • Python's SimpleHTTPServer
  • Starter files
    • github.com/maptimelex/spreadsheet-sorcery
    • Download .zip
    • Extract
    • Copy & Paste starter folder somewhere you'll remember

Geocode Addresses

function geocodeSelectedCells() {
  var sheet = SpreadsheetApp.getActiveSheet();
  var cells = sheet.getActiveRange();
  // Must have selected 3 columns (Location, Lat, Lng).
  // Must have selected at least 1 row.
  if (cells.getNumColumns() != 3) {
    Logger.log("Must select the Location, Lat, Lng columns.");
  var addressColumn = 1;
  var addressRow;
  var latColumn = addressColumn + 1;
  var lngColumn = addressColumn + 2;
  var geocoder = Maps.newGeocoder();
  var location;
  for (addressRow = 1; addressRow <= cells.getNumRows(); ++addressRow) {
    address = cells.getCell(addressRow, addressColumn).getValue();
    // Geocode the address and plug the lat, lng pair into the
    // 2nd and 3rd elements of the current range row.
    location = geocoder.geocode(address);
    // Only change cells if geocoder seems to have gotten a
    // valid response.
    if (location.status == 'OK') {
      lat = location["results"][0]["geometry"]["location"]["lat"];
      lng = location["results"][0]["geometry"]["location"]["lng"];
      cells.getCell(addressRow, latColumn).setValue(lat);
      cells.getCell(addressRow, lngColumn).setValue(lng);
* Adds a custom menu to the active spreadsheet, containing a single menu item.
* The onOpen() function, when defined, is automatically invoked whenever the
* spreadsheet is opened.
* For more information on using the Spreadsheet API, see
* https://developers.google.com/apps-script/service_spreadsheet
function onOpen() {
  var sheet = SpreadsheetApp.getActiveSpreadsheet();
  var entries = [{
    name: "Geocode Selected Cells Worldwide",
    functionName: "geocodeSelectedCells"
  sheet.addMenu("Macros", entries);

Geocoded data!

python -m SimpleHTTPServer

Start local web server

  • Open Terminal (OSX/Linux) or Command Prompt (Windows)
  • Navigate to directory you'll be working in

  • In the browser
  • That's where you'll be able to access your map locally!

Create app.js

in /js


document.addEventListener('DOMContentLoaded', function() {
    var gData
    // Spreadsheet ID
    var URL = "13Xd93PIiGvGh2JQ6uygnsUTTLAlJu7F7TE-doTy-5OY"

        callback: showInfo, 
        simpleSheet: true 

function showInfo(gData) {
    // We'll fill this function with our map and interactivity

Create map

  • in app.js
  • basemap only
 // Setup map, specifying the id of the div where the map will be located
var map = Sheetsee.loadMap("map")
// Add a basemap. We can set that with plain Leaflet
var stamenToner = L.tileLayer('http://stamen-tiles-{s}.a.ssl.fastly.net/toner/{z}/{x}/{y}.png', {
