The Google Spreadsheet™ add-on will merge the data from the spreadsheet with the Google Doc™ template. Use document mail merge for bulk letters, labels, envelopes and other bulk operations for personalizing documents. You can easily print the file after the data merge or push the personalized documents into a specific (customer/employee) folder. 

Steps in the configuration:
[1] On the Data sheet, create the relevant columns and data
[2] In the sidebar, select the document template
[3] Merge the Data and the document together
View the result in Google Drive™.

For the merge process you have the following options
 * Your file result:
 - Result in one document
 - Create a document for each data row

Your file format options:
 - Google Docs format
 - PDF (*.pdf) format

Your file location options:
 - Google Drive folder of the document template
 - Use column "Folder_ID" to determine the right Google Drive folder

File name options:
 - Use same name as the template
 - Use column "Filename" to set the File name

Note, with your Gmail.com account you only have 5 minutes, which can only merge a very few documents. Using a Google Workspace account will provide you more run time to do a document mail merge.
