PDF Data Extraction

Hello, I was working on a poc to ingested PDFs and extract data in order to store them in delta tables. As this was my first time working with PDFs, I searched over the internet and should Databricks have offering IDP, azure also have something and then there are python libraries. Since I'm working with financial data, report, etc.. One thing i noticed - the pdf format should be fixed else in most of the tools the extraction logic is either failed or we get incorrect data. I was wondering how such PDF extraction is built in real production cases and what tools are used. Please share you experi
