Google App Script to create a doc with speaker notes from slides

SlidesToDoc.gs

var INPUT_PRESO_ID = "<id>";
var OUTPUT_DOC_ID = "<id>";

function createNotesDoc() {
  var presentation = Slides.Presentations.get(INPUT_PRESO_ID)
  var out = DocumentApp.openById(OUTPUT_DOC_ID)
  out.getBody().clear();
  table = out.getBody().appendTable();
  var links = [];
  for (var i = 0; i < presentation.slides.length; i++) {
    Logger.log("Exporting page " + (i + 1) + "/" + presentation.slides.length);
    var slide = presentation.slides[i];
    var text = slide.slideProperties.notesPage.pageElements[1].shape.text;
    var row = table.appendTableRow();
    var url = "https://docs.google.com/presentation/d/" + INPUT_PRESO_ID + "/export/png?id=" + INPUT_PRESO_ID + "&pageid=" + slide.objectId;
    var imageCell = row.appendTableCell();
    imageCell.removeChild(imageCell.getChild(0)); // remove empty first paragraph
    imageCell.appendImage(UrlFetchApp.fetch(url).getBlob()).setWidth(160).setHeight(90);
    var noteCell = row.appendTableCell();
    noteCell.removeChild(noteCell.getChild(0)); // remove empty first paragraph
    table.setColumnWidth(0, 140);
    var noteParagraph = noteCell.appendParagraph("");
    if (text) {
      var textElements = text.textElements;
      var fullContent = "";
      for (var j = 0; j < textElements.length; j++) {
        if (textElements[j].textRun) {
          fullContent += textElements[j].textRun.content;
        }
      }
      if (fullContent.trim()) {
        noteParagraph.appendText(fullContent.trim());
      }
    }
  }
}

you need to provide the slides id and the document id in the 2 variables in the beginning:

var INPUT_PRESO_ID = "<id>";
var OUTPUT_DOC_ID = "<id>";

This will select the presentation (slides) and the destination document where the content will be put. The doc has to be created before you run the script.

You can amend the script to have it create the output doc if you wish, but it will make the code more complex to handle permissions and where to put the doc.

Thank you, it works great exactly as I expected !!
