maps exported save translations from translate.google.com (exported to google sheets) to a text file for custom parser of my own project

.js

// uses cell range C1:D1 to the last row
// saves  as "englishWord : chineseWord : source (translate.google.com)" for parser to interpret
function saveToTextfile() {
  var ss = SpreadsheetApp.getActive();
  var sh = ss.getActiveSheet();
  var rg = sh.getRange(1, 3, sh.getLastRow(), 2);
  var vs = rg.getValues();
  console.log(vs)

  // format data
  vs = vs.map(x => `${x[1].toLowerCase()} : ${x[0]} : translate.google.com`);

  var folder = DriveApp.getFolderById('1gKOoLeqj8EkJumTsRCQKYxsapK7hxAid')
  console.log("folder:", folder)
  var files = folder.getFiles();

  folder.createFile("savedTranslations.txt", vs.join("\n"));
}
