What’s been happening in Apps Script … The modernization of the Sheets API and the Calendar API, the release of the Slides API and most recently the Docs API have all opened up many new capabilities for Apps Script regular and advanced services. The Docs API does not yet have an advanced service so you need to go to the API directly, but as with Sheets and Slides, over time you’ll probably see one arriving along with some of the more advanced features being integrated into the regular Apps Script service. Let’s look at a few of the new goodies (and not-so goodies).
