How to prepare data for the database based on the OCR result?

Question

Database

There is an e-book in the djvu format, you need to extract the data to the database, with the help of a fine reader I extracted the text, but it turned out to be a mess that needs to be put in order so that it can be added to the database, I ruled it in the csv format, but this is very long, is there any other solution to this problem, what other options are there?
