With Form Publisher, you can generate customized documents with predesigned templates by filling them out with data submitted to a Google form or with data available in a Google spreadsheet.
An example of mass generating documents from spreadsheet data is generating personalized invoices with existing data using a predesign Google Docs template.

Procedure

1. Open the Form Publisher add-on.
   
   
   The Form Publisher sidebar opens.
   
   
2. Click START.
   
   
3. Select a sample Google Docs template.
   
   
   
   Note: You can design your own template and add markers for every column header you want to display data for.
   
4. Click GENERATE FILES.
   By default, for each row of data, Form Publisher generates a document (based on the selected template) and a PDF file.
   
   
   
   
5. Because Form Publisher does not automatically update the progress of the generated files in the add-on, keep clicking Refresh until it reports that all files are generated.
   
   
   Form Publisher adds data for each generated document in the columns  [Form Publisher] Generation Status, [Form Publisher] Generation Timestamp, [Form Publisher] Doc URL, [Form Publisher] PDF URL.
   
   
6. Click Open Google Drive folder after all documents have been generated.
   
   
   

Result

All PDF files and Google Docs documents are stored in a Form Publisher Output's Folder in your Google Drive.
