Daily Automated Google Docs to PDF Conversion
A daily conversion schedule works well for documents that are updated regularly and need a fresh PDF snapshot each day. Standup notes, daily reports, and task lists all benefit from this pattern.
Setting up a daily trigger in Apps Script
In the Apps Script editor, open the Triggers panel and add a time-based trigger. Choose 'Day timer' as the trigger type and select a one-hour window for when the script should run. Apps Script picks a random time within that window to avoid thundering-herd effects on Google's infrastructure.
Timestamping daily exports
Include the date in the PDF filename so each daily export is distinct: docName + '_' + Utilities.formatDate(new Date(), Session.getScriptTimeZone(), 'yyyy-MM-dd') + '.pdf'. This builds a natural archive you can sort by date.
What to do with the daily PDFs
Save them to a dated subfolder in Drive, email them to a distribution list, or post them to a Slack channel. The Apps Script MailApp and the Slack webhook URL are both easy to call from the same function that does the conversion.
Frequently Asked Questions
Can I run a daily conversion at exactly midnight?
Apps Script time-based triggers run within a one-hour window, not at an exact minute. For exact-minute scheduling, use the Drive API from a server-side application or a scheduled Cloud Function.
