Error "not a legal oleaut date" when reading a PDF and trying to paste all of the data into Excel

Hi everyone - I am running a bot that reads all of the data from a pdf, assigns it as a datatable, and then pulls certain data points from that datatable to be written into an excel file.

In order to determine the position of the relevant fields that i need to pull from the datatabe, I have been pasting the entire datatable into excel.

This has worked for all PDFs I have used so far, however, on the latest PDF I read it is giving me this error: not a legal oleaut date

A) Why is this happening and is there a way to fix it?
B) Is there another way for me to figure out where the relevant data I need from the datatable is positioned?
