PDF Invoice Split to Drive

I have one consolidated PDF that contains many individual invoices. Each invoice carries a unique, purely numeric invoice number. I need a reliable way to pull those pages apart so every invoice becomes its own PDF, then automatically push each file into my Google Drive.

Here’s what matters most:
• Detection must key off the numeric invoice number so the split happens at the right page break every time.
• When the file is saved to Drive the name should follow this pattern: <InvoiceNumber>_<CustomerName>.pdf (for example “10342_ABC Ltd.pdf”).
• All processing can be handled with a repeatable script or an Acrobat/Power Automate routine—as long as I receive both the working solution and the finished, correctly named PDFs in my Drive.

If you’ve done similar PDF-splitting or Google Drive automation projects with Python (PyPDF2, pikepdf), Adobe JavaScript, or other tools, let me know how you’ll tackle it and how quickly you can turn it around.
