Did you know with Google Sheets you can create your own functions that pre-populate cells? Here's a code sample to show a true or false if a website is using a certain category of technology.

/**
 * If the website has a technology in the group
 *
 * @param {domain} Root domain to lookup i.e. example.com
 * @param {type} The type of technology i.e. 'shop' or 'cms'
 * @param key Your API key at https://api.builtwith.com
 * @return True if the technology has data
 * @customfunction
 */
function BUILTWITHHASTECH(domain,type,key) {
  var url = 'https://api.builtwith.com/free1/api.xml?KEY=' + key+ '&LOOKUP=' + domain;
  var xml = UrlFetchApp.fetch(url).getContentText();
  var document = XmlService.parse(xml);
  var entries = document.getRootElement().getChildren('groups')[0].getChildren('group');
  for (var i = 0; i < entries.length; i++) {
    var title = entries[i].getChild('name').getText();
    var live =entries[i].getChild('live').getText();

    if ( title==type && parseInt(live)>0) {
      return true;
    }
  }
  return false;
}

This example serves as an example - we will provide other API endpoint App Scripts on request.
