The Google Workspace™ document add-on can be used to build documents in a consistent and quick way across your team. Via the one-time configuration in the spreadsheet, everyone can easily build documents. 

How it works
The Google Document™ add on '1-2-3 Document builder' facilitates the document creation by building your document in 3 steps:
 1. First, choice your basic document template & layout 
 2. Second, select the additional text blocks for the document 
 3. Third step, provide values for any of the placeholders in the text

You can try the add-on with the example configuration and the example documents. You would need to configure the documents and text block to your own needs.  If someone in your organization has done the configuration, you can choose the existing spreadsheet which needs to be shared to you.
