I have many PDF files created by a ScanSnap iX500. The ScanSnap also applied OCR. Within each of those PDF files, there exist separator sheets that solely contain the word “Trennblatt”. I want to split the PDF files at every separator sheet. During my research, I came across Python and PyMuPDF. Unfortunately, I don't know how to program. Is there a built-in functionality in Hazel for this task?
