Autocrat for bulk certificate generation

Autocrat is a multi-purpose document merge tool works with Google Drive. It allows you to take data from a spreadsheet and merge it into a document via a template.  Tell Autocrat which fields to merge via <<merge tags>> and then let Autocrat mass-generate personalized documents.  Users can also send the documents as email attachments. Autocrat is useful to generate certificates when conducting, seminar, webinar, competitions, quiz etc. It's possible to reuse the template for further use.

Here I am going to discuss how to create and send event certificates in large numbers using Google Drive and Autocrat.

Prepare a certificate template

First, create a folder for the certificate making purpose inside Google Drive. All files regarding the certificate save here.
Prepare a certificate from Google Slide available at Google Drive. Select a good template from there. Here First Name and Last Name put inside <<merge tags>>. Here values will load from the user's details from a spreadsheet.
