Extract text with OCR on PAD only works sometimes

Posted on by Community Power Pla... Microsoft Employee

Hi! I created a flow to extract text from PDF invoices from a particular energy company.

I used regex to locate the text from the extracted text to get my outputs.

However, the issue I faced is that the "Extract text from PDF" does not always work. For some invoices, the extracted text variable is empty. It only manages to pick up some months' invoices.

For context, these are structured PDFs and is from the same company every month.

Please help! 😞

Hi @junjie ,

Along with the flow screenshot and PDFS . Can you please confirm whether all the PDFs are scanned one or editable one.

The one which is giving empty may be the scanned pdf I guess.

The invoices might be protected. Please simply try to select some text manually in the PDF and see if you are allowed to copy it out. If you cannot do that, it means it's been protected and that will be the reason why PAD cannot extract the text.

Also, please confirm whether you really are using OCR actions. You mentioned OCR in the title of the topic, but based on your messages, it seems like you're using the normal Extract text from PDF action that does not use OCR.
