Word - Populate

Power Automate Connector: Encodian – Word

Overview

The 'Word - Populate' Power Automate action enables you to populate a Word document (DOCX) with data derived from a JSON document.

How Word Templates Are Created

To use the 'Word - Populate' action, you must first create a Word template containing placeholder expressions. These placeholders are replaced with values from the JSON data provided at runtime.
Templates can be created manually using the template syntax or generated visually using Encodian Templater.
Typical workflow:

1. Create a Word template
2. Add placeholder expressions (tokens) manually or with Encodian Templater
3. Pass JSON data and Word template into the 'Word - Populate' action
4. Generate the final document

Build Templates Visually with Encodian Templater

Encodian Templater is a free Microsoft Word add-in designed to simplify building templates for the 'Word - Populate' action. 
Instead of writing template syntax manually, generate it visually inside Microsoft Word using representative JSON data.
With Templater, you can:

• Generate 'Word - Populate' tags automatically  
• Build conditional logic using a visual interface  
• Create arithmetic expressions  
• Generate table loops from collections  

Templates created with Encodian Templater can be saved and used directly with the 'Word - Populate' action.
