Posted on by pepega

Working with a third party REST API, after making a request to the API, it returns the document content in base64 format. How do I convert it to a docx/pdf format using Power Automate?

@pepega

You can create a file in sharepoint or one drive.

You have to pass in the below format

{
"$content-type": "application/pdf",
"$content": base64returnedfromAPI
}

Open free Base64 website and choose Convert application.
Click inside the file drop area to upload Base64 files or drag & drop Base64 files.
You can upload maximum 10 files for the operation.
Click on Convert button.
Download link of result files will be available instantly after conversion.

Regards,
Bretty

I had the same problem and realised your solution. But it don't works for me. Could you have an idea what the problem is? See the seperate thread here: Convert Base64 from a RestAPI JSON into a PDF - Power Platform Community (microsoft.com)

Likewise. I'm running an HTTP GET request which returns file attachment content encoded in base64 format. This returns and object similar to the OP's post above:

{ "content-type": "application/pdf", "$content": "Base64String" }

When I use this object to create a file in OneDrive, the pdf is created, but seems corrupted. I get an error message stating: "Error:Failed to load PDF document."

This solution works for SharePoint / OneDrive, but not for "File System - Create File". We get "Forbidden" 403 when trying to create the file.
