Here is what I am trying to do:

Using the Instructions for the agent, I use GenAI to create a piece of text (e.g. a press release) and then invoke the "Create a file" action for SharePoint document libraries. At that point what I want to do is use the text created by the agent to create a Word document in the SharePoint library. However, no matter what I try to do (and I have tried dozens of iterations) I cannot get the agent to successfully create the file. It seems to get stuck and not generate or populate any viable content for {File Content} in the tool, or just keeps prompting me to upload a file, which isn't what I want.

Has anyone been able to find a path here where you can dynamically create content for a Word document and then place it on a SharePoint site?

Calling actions from Copilot Studio

Right now the SharePoint “Create file” action expects proper binary file content, but when you’re just passing text from your GenAI agent it doesn’t become a valid Word file. That’s why the action keeps asking you to upload something.

You need to create a Power Automate flow.

Your agent produces text (or HTML).
Power Automate receives that text as input.
In the flow, you either: Convert the text/HTML into a real .docx (e.g., with the OneDrive “Convert file” step) or use the Word Online (Business) connector with a template that has content controls, then populate it.
Finally, use SharePoint - Create file action to place the finished .docx into your document library.

The practical way to do what you want is: GenAI → Power Automate flow → SharePoint.

Let me know if you have already tried this and let me know if you are new to Power Automate and need help.
