How do I convert a file between formats?

Short answer: You can convert file format in ConvertAPI by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the ConvertAPI Convert File Format action to a workflow, map its 3 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.
