Save Google Docs as PDF to Drive Using Apps Script
Using Apps Script to save to Drive is the fully automated path. A short script handles the export loop, names the files correctly, and places them in the right folder. Run it on demand or set a trigger to run it automatically.
The basic script structure
Using Apps Script to save to Drive starts with opening the Script Editor from Google Drive (New > More > Google Apps Script). The script uses DriveApp to get the source folder, iterates over the files, fetches the PDF blob using UrlFetchApp with the Drive export URL, and saves each blob as a new file in the target folder using DriveApp.createFile().
Authenticating the script
The first time you run the script, Google will ask you to authorize it. The script needs access to Drive to read source files and create PDF files in the target folder. Accept the permissions for the script to run. Subsequent runs do not require re-authorization unless the permissions change.
Setting a recurring trigger
In the Apps Script editor, click the clock icon to open Triggers. Add a new trigger and set it to run your export function on a time-based schedule. Choose daily, weekly, or a specific time. The script runs in the background on Google's servers without any action from you.
Error handling in the script
Add a try-catch block around the export and file creation steps. If a document fails to export, log the error and continue with the rest of the batch. Use MailApp.sendEmail() to notify yourself of any failures after the script completes.
Frequently Asked Questions
Do I need to be a developer to use Apps Script for PDF exports?
Basic JavaScript knowledge helps. There are many ready-made scripts available in the Apps Script documentation and on Stack Overflow specifically for Drive-to-PDF exports. Most people adapt an existing template rather than writing from scratch.
