This n8n workflow automates the process of converting a PowerPoint (PPTX) file to PDF format upon manual trigger. It streamlines file conversion by downloading a PPTX file, converting it via an external API, and saving the resulting PDF directly to disk. The workflow is useful for teams or services that need to quickly convert presentation files without manual intervention.
The process begins with a manual trigger, allowing the user to start the workflow at will. A sticky note node provides key instructions, emphasizing the need for API authentication. Next, the workflow fetches a sample PPTX file via an HTTP request. This file is then sent to an API conversion service (ConvertAPI) using a POST request with multipart form data, authenticated through an API key stored in credentials. The API converts the PPTX to PDF and returns the file, which is then saved to disk as ‘document.pdf’.
This workflow can be adapted to automate PPTX to PDF conversions in various contexts, such as preparing presentations for distribution, archiving, or further processing.
