Question: I'm looking for a scalable PDF generation service that integrates with my existing tools, like Excel or Notion.

If you need a PDF generation service that can handle large volumes of data and integrate with tools you already use like Excel or Notion, PDF Hippo is worth a look. It lets developers convert Excel data into PDFs with customizable templates with data mapping that can handle large amounts of dynamic data, and it can be integrated with business tools like Excel and Notion.
