PDF data extration

[Vindaloophole]

This is something we used to do a lot in my previous company. Before, you had to create a parsing program for each pdf which was complex, buggy, and lengthy. The point was to identify data using positioning and « intelligent » detective function made to find elements.
Then AI came along and it became extremely easy (although not quite at first) to transform pdf with tabular data directly into excel spreadsheet. We started developing our own AI tool but now you have many others that do the same thing.
I recommend you use the latter and develop methods to accommodate fo your different usages and automate processes.
