Can not see Form PDF data #481

Closed shubhpy closed 1 year ago

Hey,

https://s3.ap-south-1.amazonaws.com/public-sharing-purpose/aoc_gooded_tech.pdf

I have been trying since a long time to read the data inside this PDF with any python library. Somehow I landed here.

I tried opening this PDF but can not see the data.

History: So when I open this PDF in Adobe Acrobat Reader, I see security warning of if you trust ... site and it asks to either allow or block. When I allow I can see the data. But when I open it in Preview(Mac), It doesn't ask anything and shows data.

When I passed this PDF to any Python Library (PyPDF2, tabula, PyMuPDF, pdfminer), I didn't see the data but only fields.

One day, I opened it in Preview(Mac) and exported as PDF. And Voila It was working and libraries were able to read full data.

Can anyone help me how can I see the full data in python? Thanks

@shubhpy your pdf is no more available => no analysis is possible @chiencarlos11 : the pdf is an XFA form (https://en.wikipedia.org/wiki/XFA) the form by its how is like a web page that is dynamically displayed in the viewer. The data can be extracted with get_fields()/get_form_text_fields()

This issue can be closed
