Google Slides Script for checking slides, downloading PDF and ideally having a button

[Alexander Farr]

Dear community,

I would like to create a script that achieves the three steps:

1. Some checks are performed, e.g. a) no two slides with the same title, b) checking for some certain titles are contained and if so, use a different slide for the table of contents.
2. A PDF would be downloaded directly to the users Download folder.
3. Ideally, a new menu item button would be created so that users can easily run the script.

Re 3: However, I tried using the following code and always get this error when running the code from Google App Script studio: Cannot call SlidesApp.getUi() from this context.

function onOpen() { var ui = SlidesApp.getUi(); ui.createMenu('Custom Menu') .addItem('Download PDF', 'downloadPDF') .addToUi(); }

Re 2: Also, I tried using ChatGPT to come up with the code for downloading the PDF and also get the error "Cannot call SlidesApp.getUi() from this context." for this:

function downloadPDF() { const presentationId = 'XXX'; // Replace with your presentation ID const presentation = SlidesApp.openById(presentationId); // Export the entire presentation as PDF const pdfBlob = DriveApp.getFileById(presentationId).getAs('application/pdf'); const pdfFile = DriveApp.createFile(pdfBlob).setName('presentation.pdf'); const pdfUrl = pdfFile.getUrl(); const htmlOutput = HtmlService.createHtmlOutput(`<a href="${pdfUrl}" download>Download PDF</a>`); SlidesApp.getUi().showModalDialog(htmlOutput, 'Download PDF'); presentation.saveAndClose(); }

Do you have any ideas how to fix these issues? I am new to Google Apps Script so any help would be much appreciated!

Many thanks!
