About this solution

Automatically customize the Google Slides Employee Certificate template with employee data in Google Sheets, then send the certificates using Gmail.

Employee certificate creation

How it works

The script uses the Employee Certificate presentation template from Slides and a Sheets spreadsheet with the employee details. The script copies the template and replaces the placeholders with data from the spreadsheet. Once the script creates a slide for every employee, it extracts each individual slide as a PDF attachment and sends the certificates to the employees.

Apps Script services

This solution uses the following services:

  • Drive service–Copies the Slides Employee Certificate template.
  • Spreadsheet service–Provides the employee details and updates the status against each listed employee.
  • Slides service–Replaces the placeholders in the presentation with the employee data from the spreadsheet.
  • Gmail service–Gets the individual slides as PDFs and sends them to the employees.
