Program to extract pdf to csv

Hello.
There are bank statements in pdf files.
Several types of structure type (up to 5).
All types contain a text layer, but not all libraries recognize text correctly.
In case of difficulty in extracting text, I suggest connecting ABBY finereader or opencv cloud recognition

Primarily interested in 2022.
It is necessary to extract information from PDF, structure and save it in CSV. Attached an example.
Read all PDFs from a PDF folder (may have sub-directories)
Save each statement in a separate CSV file with the same name as PDF, to the CSV folder.
It is desirable to save the folder structure, but it is not necessary.

Each entry is a separate line.

Notes:
- column D must contain only the amount without the currency;
- the + sign is not needed for amounts greater than 0;
- currency must be in column E;
- column D must contain the sum in the format 3.15 instead of 3.15, for example;

Source code required.
Project is urgent - need ASAP.
