Document automation — generating contracts, reports, letters from templates populated with data — is one of the highest-return automation scenarios available. The manual process is slow, error-prone, and adds no value.
The approaches available
Word Online connector: Power Automate natively populates content controls in a Word template with data from any connected source. Simplest approach, works well for straightforward data needs.
HTML to PDF: generate HTML content programmatically and convert to PDF. More control over layout, requires HTML skills.
Third-party connectors (Plumsail, Encodian, Muhimbi): more sophisticated template capabilities — dynamic table rows, conditional sections, complex formatting. Worth evaluating for complex scenarios.
Content controls: the foundation
In Word: Insert → Controls → Plain Text Content Control. Tag each with a meaningful name — that name is what Power Automate uses to populate it. Avoid spaces in tag names. Test formatting inside controls thoroughly.
The standard pattern
Trigger from SharePoint list item → retrieve data → populate Word template → save generated document back to SharePoint → notify relevant people. Clean audit trail: original data in the list, generated document in the library, both timestamped.
Document automation ROI is easy to calculate: time spent on manual generation multiplied by the hourly cost of the people doing it, compared to implementation cost. The business case almost always closes quickly.
Start with the simplest scenario — one template, one data source, one output format. Get that working reliably before adding complexity.
